Advantages and disadvantages of the commercial use of strong Essay

Advantages and disadvantages of the commercial use of strong cryptographic products - Essay Example Private keys are not supposed to be revealed or transmitted to any other individual. On the other hand, secret-key systems have to be transmitted through a communication channel or manually since the same key used for decryption is also used for encryption. In this case, the might be serious threat of an enemy discovering the secret key when it is being transmitted (Guo and Jin 2011). In addition public-key systems can provide signatures digitally thus preventing repudiation. During authentication through secret-key systems, there is the need of sharing secrets and in other cases it requires the involvement of a third party. This third party can go against the other members and repudiate a message that was previously authenticated and claim the shared secret was compromised. For example, a company may involve a central database that keeps copies in its secret-key system authentication. If this central database is attacked, a widespread forgery on the product of this company would occur. Public-key authentication can prevent this forgery and secure the products of the company. Cryptography has the disadvantage of speed during encryption. Some encryptions methods are faster than others but they take time to encrypt. In order to maximally reduce the time used during encryption, it is advisable to combine several methods to obtain security advantages and speed. This is done by using public-key systems together with secret-key systems. Public key-systems have the advantage of security while secret key systems have the advantage of speed. This protocol is normally referred to as digital envelope (Mollin 2001). The creation of the code used in the encryption and decryption process takes time. For one to figure out the best code to use they have to be an expert in that field and at the same time is patient. This makes the process of make the process of cryptography a hectic and tiring one. In the past sending a code from one person

Balance in the Administration of Justice and Security Essay

Balance in the Administration of Justice and Security - Essay Example This is because of the change in technology and new laws that aid in balancing the two. New laws have been formed and implemented in order to protect the rights of citizens while still offering them security. Some of these laws include different and less torturous methods of punishing the offenders. There have also been several changes in the constitution. Many rights have been included in the constitution in order to maintain peace by creating a stable balance. Mass media and technology have helped in the balance. The issues concerning legal environment have been enacted in the constitution in order to grant citizens justice and security. Balance is very important in all the countries in order to maintain peace and order. Introduction The introduction of new laws and policies has helped in the evolution of justice and security in the 21st century. Many countries have established new policies that govern how civil and criminal activities are handled. The countries have also increased surveillance in order to minimize such cases. For example, the United States government has formed an anti terrorist act in order to prevent crime. The people working in the law enforcement and security sides have to make sure that they are not abusing the rights of victims or criminals while working on their cases. Justice should be a natural right. In social environment, justice must be natural. The actions of the police have to be in relation to this statement. Their role in the system has to be governed by this goal of the justice system. Justice involves digging deep down into the issue in order to deliver justice. In order for police to administer justice, they have to take no sides whenever investigating an issue. Selflessness will assist them in maintaining law and order (Alexander, 2003). They should have passion in their doing in order to achieve this. According to the constitution the police should present service of justice with loyalty. Before, the police used to admin ister justice in the favor of the rich and wealthy. Very few wealthy people used to be arrested or even sent to jail. With the new laws and policies that have evolved in the 21st century, the administration of justice by the police is based on the balance of justice and security. The rich are at a low risk of going to jail unlike the poor people. This has been so because the rich are able to hire top lawyers. In very few cases we hear the rich people in our communities go to jail. They are always given the lowest charges. For example, many celebrities all over the world are found with many illegal commodities like guns and drugs. Most of these celebrities are charged with the shortest term in jail. On the other hand, the poor people are the ones who are punished more. This is because they are not able to pay lawyers like the rich. This was the case in the past few years. Even if some of these cases still exist, the evolution of the balance in the administration of justice has helped minimize these cases. All governments now have lawyers who represent the poor people in the community. The poor are now able to express themselves in a court of law. Torture which was one of the main methods that the police used in many countries was abolished. Torture was seen as the quickest means of obtaining information from people. By doing so, they made sure that justice was
