Mongol Change and Continuity

Matthew Choi Period 4 11/25/12 MONGOLS CCOT ESSAY The Mongols were a vast and influential empire that spread throughout Eurasia. From the time of Genghis Khan to the Yuan dynasty, the Mongols experienced numerous changes in their lifestyle and leadership as they strayed from their nomadic ancestry. However, while they experienced some changes, they still clung tightly to their culture until the end of the empire. Genghis Khan was the founder and emperor of the great Mongol Empire, and as a result, it became the largest contiguous land empire in all of history.Genghis Khan sought to unify the Mongols, and conquered nomadic Mongol tribes, unifying them at Karakorum, the capital of the Mongolian Empire. Whether on the battlefield or at home, Genghis was famous for his ruthless brutality. For example, when he defeated Mongol clans, he boiled all of their chiefs alive while killing all males taller than a wheel. As a result, he struck fear into the hearts of men women and children, and al l that he opposed viewed the Mongols as an invincible empire.In 1211 Genghis Khan broke through the Great Wall of China, which the Chinese thought was an ultimate defense; but when Genghis pierced it, they were terrified by his seemingly undefeatable army. He spread his influence across central and Southeast Asia during his reign, but he could not conquer Japan because of divine kamikaze winds and the Mongol fleet was destroyed. This proved that the Mongols were not an invincible force, they could be killed, and this shifted the peoples view on the Great Khan.The Pax Mongolica, or â€Å"The Mongolian Peace† was a time period that lasted for about a century during the Mongol Empire. During this time, intercontinental trade flourished because of the reopened trade routes, including the Silk Road. This time period is also used to describe the stabilization of the Mongol culture. While traveling through the routes and conquering other lands, the Mongols kept to their nomadic ance stry. They lived in Mongol yurts, which were portable dwellings made of pelts and ooden poles, and these were ideal for nomadic travel. The geography of Central Asia consist of deserts and grassy landscapes, where agriculture is hard to support. The nomads focused on the domestication of strong and healthy grazing animals so the Mongols would have enough food, shelter, and clothing. Mongol nomads travelled often, and they had to use the teachings of their ancestors in order to survive. Genghis Khan’s knowledge of his nomadic ancestry is probably one of the biggest reasons why the Mongolian army was so successful.

The internship assignment - Essay Example The internship assignment The customers need their ordered products on time and therefore, vendors have to attain a certain levels of synergy and coordination among various departments in order to achieve the desired outcomes of a specific project. The job that was performed during the internship was all about conforming by the deadlines. I managed to perform the job quite well as I was able to promote teamwork and synergies among the entire workforce. It was significantly challenging for me to combine various members from several departments in order to build cross-functional teams. The team developmental process was halted and jammed more than a few occasions. The difficulties were faced because there was a presence of particular distaste and unwillingness towards the notion of working closely among technical and managerial staff. Both of the groups held on to the point that the other group does not have necessary information needed to comprehend the issues. But I with the help top management sponsored a le arning environment in the overall organization and therefore, played a significant and important role in the completion of delayed projects. My job as a coordinator in a software development company assisted me to get important knowledge about the global industry of software development and sales. The industry has spread in all parts of the world and due to this reason I have gotten an unforgettable chance to interact and communicate with people from various cultures and nations. As a sales representative, I have also noticed a few marked differences in the behavior of people from under developed and advanced nations respectively. The customers belonging from formerly mentioned group of nations set a premium on cost effectiveness of information technology solutions. The buyers from latter type of countries focus on quality and they are least concerned with the price tag of the product. The clientele of the company where I worked is culturally and regionally dispersed. I have found Americans with very professional attitude and they were extremely lenient in terms of providing extension in deadlines. The Chinese and Russian s on the other hand, were very aggressive in handling delays. In short, I have come to recognize that the population of developed nations is far more polite and humble. But the customers from less developed nations are very annoying and they got on my nerves on more than one instances. Yet I remained calm and composed while handling their grievances. More specifically, I have learned that the culture is the software of human mind (Hofstede & Hofstede, 2010) and therefore, people use their cultural and economic experiences for making decisions. The economic conditions of the less developed world have been continuously degrading. The abovementioned trend has forced companies in less developed world to outsource technology to more developed ones. But the companies from less developed world are highly sensitive towards prices and therefore, they always search for the cost effective technological solutions. I have also learned that those companies with poor computer and technological lit eracy cannot use the solutions to the full extent. Nevertheless, I will propose intensive technological training to all companies that are looking to acquire latest infrastructure. In my view, state of the art technology is useless until the staff knows how to use it. In the case of major number of the companies, technology results in less

Organisational Ethics in OPEN24 Essay Example | Topics and Well Written Essays - 1750 words

Organisational Ethics in OPEN24 - Essay Example For a company organization is a means to an end in order to achieve its goals. In this sense, organizations can be distinguished into two fundamentally different sets of objectives: The team of financial advisors is highly focused, trained up and very aggressive sellers, they concentrate on non walk-in customers and their objective is the selling of business loans. Increasing competition in the marketplace combined with rather draconian cultural internal problems such as bureaucracy, poor communication, and perceived lack of personal job advancement possibilities has led the employees to high levels of frustration many times in the past. 'All organisations begin with some sort of Vision, an initial spark which causes its creation. The organisation's Vision is essentially the dream which unites a core group of people and inspires them to try and make the dream a reality.' We can say that Open24 has a vision on what it wants to achieve in the near future. All employees work towards these visions and indeed if they work as group, then there is no reason as to why they should not achieve their organisational goals. Open24 organisation's pur...'All organisations begin with some sort of Vision, an initial spark which causes its creation.

We can say that Open24 has a vision on what it wants to achieve in the near future. All employees work towards these visions and indeed if they work as group, then there is no reason as to why they should not achieve their organisational goals. (Ping, 1996)Â   Open24 organisation's purpose grew from their vision and in articulating its mission; they should have stated how it will seek to bring the vision to reality. 'It is stating what its 'Unique reason for being' is, and what the values are that will give meaning to its purpose.' (Ping, 1996) When it comes to organisational ethics, it is here in the mission statement that the seed is planted which gives rise to the 'shared set of beliefs' that will determine the organisation's climate of opinion. (Ping, 1996)Â   The main problems that the department faces and can prevent from the above mentioned plans are the following: Strict Management that creates employee dissatisfaction thus, high employee turnover ratio.Poor communication.

International Business and operations Management Essay

International Business and operations Management - Essay Example In China there are many existing domestic firms (over 8,000) engaged in the production and sale of agricultural equipment while a substantial number of international reputable firms have made major inroads into the Chinese farm machinery market. To understand international business ventures, Peng et al (2009) through their unified international business framework suggest two approaches in understanding international business frameworks. These are the institution-based view whereby the foreign venture firms aims at developing an understanding of the local business environment; and the resource-based view in which the firm utilizes its competitive advantage like superior technology or products to gain a foothold in the local markets. China as one of the fastest developing emerging markets provide a highly developed potential market for agricultural equipment due to its large population and lowly mechanized farming methods hence is a viable entry point into the Asian region market. International strategic management mainly encompasses firms engaged in cross-border trade globally that usually take advantage of local resources in diverse geographical locations to enhance their productivity and returns. Lessard (2003) has identified four strategic frameworks that distinguish these international firms: geographic span of the particular industry; the pull of the specific locations including the markets, resources, and the competitive edge; upholding of the international strategy; and the extent of global incorporation including the localized spread. The western and northern parts of China however have not greatly enjoyed the rapid growth experienced in other regions of the country. The government has therefore consequently provided incentives to foreign firms interested in expanding in these regions in form of lowered statutory requirements and other inducements as well as providing a high-quality communication and

Intelligence Reform Essay Example for Free

Intelligence Reform Essay Brief Background The aftermath of the 9/11 tragedy has caused the US Federal Government to re-assess the setback and possible flaws of their homeland security defense. To primarily focus on investigating the tragedy, in November 27th 2002, the US Congress and President Bush commissioned a ten-man panel that comprised the National Commission on Terrorist Attacks Upon the United States, which is known as the 9/11 Commission.   The 9/11 Commission expedited the investigation process and came up with a two-pronged framework based on the assessment. This two-pronged framework consists of the framing of action at a global perspective and the formulation of action at the domestic domain. The homeland security aspect has been emphasized and related by the 9/11 Commission with strong urgency for implementation and recommended it to Congress and the President. In addition, the commission also suggested the enactment of immediate measures that deal with the intelligence and enforcement agencies and the military organizations. Moreover, the US government has enacted several inter-agency programs that are highly supported by Congress and President Bush. Thus, the nationalization of homeland strategic programs has formally resulted in the Intelligence Reform and Terrorism Prevention Act (IRTPA) on January 20th 2004. In this regard, this paper will discuss the intelligence components of the IRTPA and measure its performance throughout the intelligence community while comparing it with the recommendations of the 9/11 Commission. On these bases, a conclusive evaluation will discuss the impact of IRTPA to reform the national intelligence community. An Update Briefer This update briefer is used to keep abreast with the situation of the intelligence reform in retrospect of the discussion throughout this paper. The paper will also form relevance to the background of concerns affecting the IRTPA. Basically, according to critics, â€Å"the Bush administration is in its seven years of intelligence fiasco which controls more than 80% of America’s $60 billion intelligence budget—reflective of Secretary of Defense Robert Gates’ streamlining the Pentagon’s trail on national security policy and intelligence as he work hand in hand with Director of National Intelligence (DNI) Michael McConnell—he gradually assert civilian control over the key spy agencies funded by the defense budget and held Pentagon’s effort to create its own intelligence machinery independent of the CIA† . This criticism could somehow be founded on the discretion of the President and put into perspective the 9/11 Commission Recommendation No.13.2 which states that: â€Å"the current position of Director of Central Intelligence (DNI) should be replaced by a National Intelligence Director (NID) with two main areas of responsibility; (1) to oversee national intelligence centers on specific subjects of interest across the U.S. government and (2) to manage the national intelligence program and oversee the agencies that contribute to it† . At hindsight, the intelligence fund may have lead to criticism because the teaming up of Pentagon with the CIA requires substantial budget allocation primarily due to the realignment of budget appropriation to intelligence activities. The Framing of Global Strategy This section of the paper will discuss the 9/11 Commission’s framing of global strategy that defines the action of security measures at international perspective, as follows: Reflection on Generational Challenge The 9/11 Commission has determined and defined the conceptual framework of knowing their enemies by familiarizing the historical origin and doctrines that instilled in their adversaries desires to wage war against America. Basically, familiarizing with the enemy is also familiarizing with the combative measures used in defining or assessing the formidable threat. It was found that terrorism is not only an act of vengeance to kill and destroy but is also based on the doctrines of Islamist secessionism which means that the allied forces and not only America is at risk of terrorist attacks. In this regard, familiarizing with enemy requires the use of all elements of national power: diplomacy, intelligence, covert action, law enforcement, economic policy, foreign aid, public diplomacy, and homeland defense. By reflecting on the situation and knowing the enemies, the challenge lies on the achievable tactical and strategically managed plan of action for short and long term implementation. Attacking terrorists and their organizations The collaborative diplomatic ties with allied governments focuses on a campaign to thwart the terrorist attacks by means of information exchange and expanding the open-source of intelligence information, intensifying military operations and sharing of financial resources to allied government’s counter-terrorism programs.   The conduct of war on terrorism has been installed at all frontiers of defense ranging from domestic and international boundaries. The strategy being employed is to know better the enemies but more on identifying the perpetrators of terrorism. The coercive action in condemning the so-called â€Å"cowardice attack to US soil† has been proven in the fall of Baghdad and the capturing of Iraqi tyrant Saddam Hussein, a close ally of al-Qaeda leader Osama Bin Laden. The war on terrorism is treated with broadened understanding by the 9/11 Commission. Preventing the Continued Growth of Islamist Terrorism According to former US Defense Secretary Donald Rumsfeld , the battle of ideas is between the question of enforcing law to prevent terrorist attacks and the question of just merely killing them the moment they commit the crime. Capturing terrorists, whether they are suspected or proven otherwise, would strategically achieve security defense. In addition, isolating the enemy and putting them into peripheries is another tactical form of beating them.   In contrast to Rumsfeld’s claim, the 9/11 Commission has tackled the importance of the UN’s declaration of human rights and some principles on Articles of War of the Geneva Convention. It briefly explains the humane treatment of the enemy of the state even when they are captured in combat zones—as mostly terrorist prefer to hide in strife-torn areas—or at the actual scene of the crime which are non-combat zones and urban population areas. In a way, the act of capturing an enemy is employed with strategic treatment and debriefing on the circumstance of indoctrination, specifically to familiarize with the Islamic doctrines in a tactical aspect. At a glance, it is a minimal gain to extract information from a captured terrorist because most of them are suicidal and would rather bring with them to their grave the classified information they know or possess. In relation to adopt more sustainable strategies at the global perspective, a 6-point framework is as follows: 1. Turning a national strategy into a coalition strategy refers to fostering a broader alliance in various governmental representation from its domestic or homeland relations to international cooperation; 2. Proliferation of weapons of mass destruction refers to supporting the call of the UN Security Council to all members and all allied states to disarmament of lethal weaponry that may result a genocide of the human race; 3. Strengthen counter proliferation efforts refers to act on counter-measures for countries that condone the exchange of lethal weaponry or weapons of mass destruction; 4. Expand the proliferation security initiative refers to expanding the open-source information in aid of intelligence access and exchange; 5. Support the cooperative threat reduction program refers to the retrieval of potentially useable weaponry or armaments that has been stockpiled during the war—which may be availably used by terrorists; 6. Targeting terrorist money refers to acting on financial embargo or halting the financial flow on the nature of funds that is being used by terrorists in funding their terrorist activities. Protection and preparation for terrorist attacks The continuing assessment and monitoring of potential threats of terrorist attacks to US homeland in particular and international communities of allied governments in general are being put into heightened configuration of security measures. The stabilization of preparedness programs and protective laws on immigration would minimize the burdens of terrorist threats. The crossing of borders is employed with modernized technological facilities and physical security system that would limit the terrorist’s mobilization or in-and out-country deployment. Likewise, travel advisory reduces the vulnerability of citizens to plunge into hotspots or terrorist bailiwicks. Defending the Homeland The 9/11 Commission has formulated recommendations with encompassing urgent actions for the US government to consolidate and mobilize troops and agencies. The key functional agenda is patterned after the global strategy that tackled the US homeland defense system. The following are the recommendations based on â€Å"How to do it? A different Way of Organizing the Government† : Unity of Effort Across the Foreign-Domestic Divide The recommendation called for jointly undertaking action in the sourcing of integrated intelligence through the establishment of a National Counter-Terrorism Center which has a mandate that resembles the Terrorist Threat Integration Center. The NCTC manages the joint operational and intelligence activities. Unity of Effort in the Intelligence Community Streamlining the flow of intelligence by organizing the key positions of authority, in which a National Intelligence Director manages the joint operational and intelligence centers, replacing the CIA’s Director of Central Intelligence. Unity of effort in Sharing Information The President’s mandate is called for unifying the functions of the government through mobilizing all governmental agencies to engage in information gathering and international cooperation with allied governments for information sharing. Unity of Effort in the Congress This calls for the establishment of a fully functional Congressional body that creates strong security policies and strengthens the homeland security. The unity of effort in Congress creates a policy structure that addresses the judicial and legal processes of security measures that manifests the sovereign interest of the people. Organizing America’s Defenses in the United States Institutionalizing the framework of intelligence—aside from the existing intelligence agencies—through a unified and managed specialty agency that is mandated to specifically organize the homeland defense basically results in the creation of the Department of Homeland Security. Transforming the Intelligence Work and Issues on Reforms In January 20th 2004, the US Congress enacted the Intelligence Reform and Terrorism Prevention Act of 2004 (IRTPA). The primary purpose of IRTPA is to reform the intelligence community and the intelligence and intelligence-related activities of the United States Government . The transformation of intelligence work has found relevance in the enactment of IRTPA, in which the Office of the Director of National Intelligence (ODNI) has worked closely in the framing of the IRTPA as a law. According to ODNI, â€Å"a great structural change has occurred in the passing of IRTPA† . Stressing on the structural change, the ODNI has reformed its capabilities in managing the flow of human intelligence (HUMINT) as their open-source of information. Reforming the capabilities also enabled the optimization of both human and financial resources in managing the operations. The reform in the ODNI has substantially addressed the key operational issues affecting the intelligence community and is abl e to put into perspective the intelligence work on counter-terrorism, in order to fully manage the homeland defense system. In a Senate inquiry on the progress of intelligence reform in January 23rd 2007, the ODNI was inquired with several issues. First, they were asked about the agency performance in which Sen. John Warner pointed out â€Å"the progress thus far achieved by ODNI is ten percent† . Second, they were questioned on the effectiveness of managing the clandestine operation of the CIA using the HUMINT (human intelligence) in information sharing from open-sources, which apparently still need more refinements from the point of view of organizational management. Furthermore, the performance of the ODNI, as it reported its achievements, has shown defects in its organizational aspect. Due to these defects, the Senate inquiry hinted on an organizational review and suggested the recall of the clandestine operation as further inquired on the assurance of the best intelligence from the Iraq Study Group (ISG), which have achieved tactical and strategic intelligence. The conclusion of the Senate inquiry presumed on the issue of reform, which does not manifest in the ODNI’s organizational capability to benchmark the achievements of goals and the CIA’s clandestine work. A brief review of the literature shows that the ODNI may have been in the stage of adaptability to the structural change embodied in its organizational mandate by virtue of the IRTPA. Another consideration is the underlying performance of the ODNI in streamlining its goals which has affected the benchmarking of short and long term operational plans in the field and which has merely given due management by the CIA in its clandestine operation in using the HUMINT. At this point, the reform in intelligence community work was supposed to be measured by the expected assertiveness of the ODNI—as the 9/11 Commission recommended that the ODNI be designated as the agency that implements joint operational and joint intelligence work and replace some aspect of intelligence work of the CIA. Retrieval of Operation to Manifest Reform In an effort to fully address the key issues to manifest reform in the structural change brought about by IRTPA and legislative pressures, the retrieval of operation in the organizational function of ODNI has been resolved by the US Senate through the approval of the Fiscal Year 2008 Intelligence Act which â€Å"would emanate a more aggressive role to the ODNI in coordinating with the intelligence community† . The Senate Bill has surpassed the ODNI’s will of authority and retrieval of its operation that is being realigned to fully act on its function as a frontline agency in executing its mandate given by IRTPA. The degree and scope of authority of the ODNI is then expected to ventilate the reform in the intelligence community so as to re-examine the burdens and defects of work ranging from ministerial execution to field implementation. Moreover, an added feature that empowers the ODNI is the streamlining of bureaucracy in the formulation and execution of operating plans. Basically, reducing the involved authorities may expedite and resolutely implement the overall function and coverage of intelligence work. Likewise, the ODNI has been given the authority to appropriate budget thereby earmarking the fund for its National Intelligence Program. It would then be up to the ODNI to utilize and mobilize the resources that would be used to reform in the intelligence community. Conclusion The determination and identification of the 9/11 Commission for a global strategy has basically created the framework for the US homeland defense system. On the other hand, the recommendations have strongly moved the US government’s Executive, Legislative, and Judiciary branches which have enacted the IRTPA of 2004. In addition, the ODNI, as the body acting on intelligence mobilization, would require substantial budget allocation. Analyzing the enactment of IRTPA may be likened to a sword and an armor in which the bearer is the ODNI. In this regard, it can then be said that the US government has created an executioner of war on terrorism. Moreover, the degree and scope of authority vested upon the ODNI may be perceived as an ultimate implementer of capturing the world’s update. However, in some degrees, the reform in intelligence community may be burdened by domestic resistance from figures belonging to allied governments that oppose US foreign policy. Generally, the reform that was achieved by the US homeland defense system is the consolidation of its intelligence enforcement agencies and mobilization of its resources and strategies towards global perspective. The re-structuring of intelligence framework may be described as an art of war or a one-step backward, two-step forward move, which pursues the enemy outside its homeland while minimizing casualties. With this perception, the war on terrorism has been brought to the backyard of allied governments. It may be additionally perceived at the militarist point of view that the reform in intelligence community could reduce the expense of war in order to achieve the socio-economic-political gains from the war zones.

An Introduction To Encryption And Decryption

An Introduction To Encryption And Decryption CHAPTER 1 This thesis proposes a VHSIC Hardware Description Language (VHDL) design of Encryption and Decryption Algorithm for Data. In this chapter, the challenges of cryptography is firstly presented. This chapter also briefly discusses the problem definition, scope of work and the thesis objectives are also highlighted.Finally, the chapter end with the chapter organization. The dissertation presentation is provided at the end 1.1 An introduction to Encryption and Decryption, a type of cryptography Encryption and Decryption, a type of cryptography, refers to the process of scrambling information so that the observer cannot be detecting the data. Cryptographic key is a piece of data used to encrypt or decrypt to plaintext. (Alex Brennen V., 2004) The Crypto, from the word cryptographic mean is it has its origins in the Greek word KRUOTOS, which means hidden. Thus the objective of cryptography is to hide information so that only the intended recipient can read it.[2] . Cryptographic is a protocol or method of performing encryption and decryption (Alex Brennen V., 2004). There are two types of cryptographic: symmetric and asymmetric key. Figure 1.1 is example a symmetric cryptographic has a single key, which is used for both encrypting and decrypting information. Data Encryption and Decryption is a well-known example of symmetric cryptographic. In symmetric cryptographic, public-key cryptographic uses complementary pair of keys to divided the process of encryption and decryption. This process is shown in Figure 1.2. This part is discuss about the symmetric-key cryptographic only.[3]. The proposed projects is to create the algor ithms where it is use to convert of information, rearranging the original massage produce output referred as ciphertext Plaintext Plaintext Ciphertext Key Figure 1.1: Symmetric Cryptographic Plaintext Plaintext Ciphertext Encryption Key and Decryption Key Figure 1.2: Public-Key Cryptographic 1.2 Problem Statement At present there are many encryption and decryption, especially in the communication system provided in a variety of application. Encryption and decryption is particularly impacted in the field of military communications and reliable security data to protection for transmitting. This ciphertext is used in the military is to send information such as direction, strategy, secret codes and other information that can not be know by the national foe during the war.[4] Creating this system is the process by which information can not be detect by the national foe. The information can not be recognizing by the national foe because this system is using the process to encrypt data and decrypt data.

Overview This chapter is to introduce the host range of background information and research for this thesis. Most methods have been widely used to determine how the process of encryption and decryption. Theoretical method is presented using the VHDL. Chooses the VHDL programming for design encryption and decryption because this programming is very direct forward is compare other programming. For example Cadence and C++ programming. Both programming is very complicated. In this chapter, the Literature review of the research is discussed. The main topics discussed in this chapter are shown below: Symmetric cryptography Encryption Decryption Operations of Encryption and Decryption Data Encryption and Decryption VHDL (VHSIC Hardware Description Language) 2.1. Symmetric key cryptography The symmetric key scheme is the conventional method of cryptography. The scheme uses the similar key to encode and decode in information. In a symmetric key algorithm, in the normal case, the communication only uses only one key. For example if Z user Z sends the secret symmetric key to an X user before the start of the communication between them. Part Z and X use the same symmetric key to encryption and decryption the message. Encryption and Decryption are example of symmetric key algorithm. Figure 2.2 shows the symmetric key cryptography. The symmetric key algorithm is faster than an asymmetric key algorithm. There are two classes of symmetric key cryptography as block ciphers and stream ciphers. [6] Plaintext X Plaintext Z Encryption and Decryption Symmetric Key Figure 2.1: The symmetric key cryptography 2.2 Block Cipher Block cipher is a type of symmetric-key decryption and encryption algorithm. The symmetric-key decryption and encryption that is a fixed length block of plaintext data into block ciphertext data. The block size is 64 bit. The block size can be upgrade to 128 bit, 256 bit or 512 bit if the process becomes advanced. Block ciphers operate on large blocks of data. The encryption and decryption of plaintext with a block cipher will result in the same when the same key is used. From the figure 2.3, it can be seen that show the Block Cipher Plaintext Plaintext Block Cipher Encryption and Block Cipher Decryption Symmetric Key Figure 2.2: Block Cipher 2.3 Stream Cipher Stream cipher is a type of symmetric encryption and decryption algorithm. Stream ciphers much faster than any block cipher. Stream ciphers operate on smaller units of plaintext. The encryption and decryption of plaintext with a stream cipher will result in the same when the same key is used. From the figure 2.3, it can be seen that show the Stream Cipher Plaintext Plaintext Stream Cipher Encryption and Stream Cipher Decryption Symmetric Key Figure 2.2: Stream Cipher Advantages of Symmetric Key Cryptography The main advantages of symmetric key (public key) cryptography are improved security and expediency. Other major advantages from the symmetric key (public key) are that they can provide a technique for digital signatures. Verification via secret-key system requires a shared secret and sometimes requires trust of a third party. For example, Kerberos verification system involves a button-secret data center that stores copies of all user secret key. An attack on the database will enable the falsification of the system. Public key verification, on the other hand, prevents of rejection, and each user has a responsibility to protect his private key. [7] 2.3 Disadvantages of Symmetric -Key Cryptography The disadvantage of symmetric cryptography is that it presumes two parties have agreed on a key and been able to exchange that key in a secure manner prior to communication. This is a significant challenge. Symmetric algorithms are usually mixed with public key algorithms to obtain a blend of security and speed. Disadvantage of using symmetric-key cryptography for encryption and decryption is faster. There are popular secret-key encryption and decryption technique that are considerably faster than any at present available symmetric-key encryption and decryption technique. However, public-key cryptography can be used by means of secret-key cryptography to obtain the optimum of both worlds. For encryption, the optimum solution is to join together with public-key and secret-key systems in order to obtain both the security advantages of public-key systems and the velocity advantages of secret-key systems. The public-key system can be make use of to encrypt a secret key which is make use of to encrypt the bulk of a information or message. Public-key cryptography may be vulnerable to impersonation, although, also furthermore if usersà ¢Ãƒ ¢Ã¢â‚¬Å¡Ã‚ ¬Ãƒ ¢Ã¢â‚¬Å¾Ã‚ ¢ private keys are not available. A successful assail attack pounce on a certification authority will permit a national foe to impersonate whomever the adversary pick out to by using a public-key certificate from the compromised authority to bind a key of the national foe choice to the name of another user In some plight, public-key cryptography is not obligatory and secret-key cryptography alone is enough. This belonging to environments where secure secret-key assent can take place, for example by users confluence in private. It also belonging environments where a sole authority knows and manages all the keys. Formerly the authority knows everyoneà ¢Ãƒ ¢Ã¢â‚¬Å¡Ã‚ ¬Ãƒ ¢Ã¢â‚¬Å¾Ã‚ ¢s keys already there is not much excess for some to be public and others private. And yet, public-key cryptography is normally not obligatory in a single-user environment. Example, if want to keep personal message or information encrypted, can do so with any secret-key encryption algorithm using personal password as the secret key. Furthermore, public-key cryptography is optimum equivalent for an open multi-user environment. Public-key cryptography is not intention to substitute secret-key cryptography, but nevertheless to complementary it, to make it more safety [8] 2.4 Encryption Encryption is a form of cryptography that to change the plaintext into ciphertext. A cipher is a algorithms for the encryption. Encryption is the principle of such security step as digital signatures, digital certificates, and the public key infrastructure. Computer-based encryption method use keys to encrypt and decrypt information. A key is in binary number. The key is one part of the encryption process. It must be used in connection with an encryption algorithm to generate the cipher text. Encryption is the symmetric or asymmetric. Ciphers were repeatedly used directly for Encryption without supplement procedures such as ratification. The extremely used kind of encryption is symmetric Encryption, which is aptly named for the reason that it uses one key for both the encryption and decryption system [9] 2.5 Decryption Decryption is the opposite or moving from the ciphertext back to the plaintext. A cipher is a algorithms for the decryption. The specification operation of a cipher is to manage with both by the algorithm and in each example by a key. Decryption is the symmetric or asymmetric. Ciphers were repeatedly used directly for decryption without supplement procedures such as ratification. The extremely used kind of decryption is symmetric decryption, which is aptly named for the reason that it uses one key for both the encryption and decryption system [10]. 2.6 Operations of Encryption and Decryption An encryption and decryption scheme consists of three Standard algorithms: A Key Generation Algorithm. For a symmetric key, this is often an algorithm that simply picks a random key of a certain length. The symmetric key scheme is the conventional method of cryptography. The scheme uses the similar key to encode and decode in information. An Encryption Algorithm. This takes as input a message (or plaintext) and some kind of key, and outputs a ciphertext. Encryption is to change the plaintext into ciphertext A decryption algorithm. This takes as input a ciphertext and some kind of key, and outputs a message.Decryption is to change the ciphertext back to the plaintext 2.7 Data Encryption and Decryption This system works by encrypting and decrypting groups of only 64 message bits, which is the same as 16 hexadecimal number. To do the encryption and decryption, this system uses symmetric keys where are also apparently 16 hexadecimal number long, or 64 bits long. However, every 8th key bit is ignored in this algorithm, so that the effective key size is 56 bits. But, in any case, 64 bits (16 hexadecimal digits) is the round number upon which Encryption and Decryption is organized. The process is explain in Figure 1.2, it can be seen that the process of encrypt and decrypt, if take the plaintext message is 2872762F771B15E8, and encrypt it with the key 0000000000000001, the ciphertext produced 1234567890987654. If the ciphertext is decrypted with the same secret key 0000000000000001, the result is the original plaintext 2872762F771B15E8. Input data 2872762F771B15E8 Key Encryption Ciphertext 123345678890987654 Key Decryption Key Original input 2872762F771B15E8 Figure 1.2: Simple Block Diagram Process Encryption and Decryption using Feistel Algorithm 2.4 VHDL History (VHSIC Hardware Description Language) In order to complete the design, the VHDL is one of the most important tools used. Device description language VHDL is a great acronym stands for the Very High Speed Integrated Circuit Hardware Description language. It was originally developed on the orders of the U.S Department of Defense. They need a more efficient way to document the behavior of the ASIC design service companies were present.[11,12] It was developed as an alternative to the huge, highly complex manuals that were the norm. The idea to simulate such a description was immediately an attractive prospect and logic simulators were developed could take a VHDL description as input. From here synthesis to the hardware level became a focus of study and still is. Current state-of the- art synthesis tools can create hardware for a large subset of the VHDL language and should at least support the synthesizable subset in IEEE1076.6-1999. The syntax of VHDL was derived from Ada, with constructs added to handle the parallelism th at appears in hardware designs. The language is strongly typed and case insensitive. [13,14] The initial version of the language that was presented in the IEEE standard 1076-1987 was somewhat limited and a new version appeared in 1993 in IEEE standard 1079-1993, which improved the consistency of the language. There have been various reviews and updates to the standard of the languages since, but the 1993 version is the most prominent and widely used. Both versions of the language ignored the need for a multi-valued logic type which is where the IEEE standard 1164 comes in.[15] This standard defines a 9-valued logic type called standard logic. This has become the standard type to use for multi-valued logic in VHDL descriptions. The language has been further extended in a series of libraries. One such library is the numeric std library which implements a signed and unsigned type. These types allow for arithmetic to be performed on arbitrarily sized logic vectors. [16] 2.4 VHDL (VHSIC Hardware Description Language) In order to complete the design, the VHDL is one of the most important tools used. Device description language VHDL is a great acronym stands for the Very High Speed Integrated Circuit Hardware Description language. It was originally developed on the orders of the Department of Defense. They need a more efficient way to document the behavior of the ASIC design service companies were present.[ represented 11,12] VHDL (VHSIC Hardware Description Language) was originally adopted by the U.S Department of Defense. The initial version of VHDL, designed to IEEE standard 1076-1987, included a wide range of data types, including numerical (integer and real), logical (bit and boolean), character and time, plus arrays of bit called bit_vector and of character called string.
