- A government agency determines that encryption is necessary to safeguard communication between itself and its overseas counterparts. It is agreed at a meeting with its rivals to create a proprietary encryption algorithm for this reason. Is this judgment justified? What dangers are being accepted?Are there any advantages and disadvantages related with the use of symmetric encryption techniques? What kinds of things should be taken into account before deciding on a certain method of encryption to put into practice?Are there any advantages and disadvantages related with the use of symmetric encryption techniques? What kinds of things need to be taken into account before deciding on a certain kind of encryption to put into action?
- Using asymmetric encryption methods, such as those found in public-key cryptography, is a prudent move that should be taken. The use of public keys within the realm of cryptography is proof of this fact.First, argue for the best information security practice, whether a block cipher or stream cipher should be used to encrypt a video data file sent through the internet as part of a major, successful entertainment service. The entertainment company has a large market share, and ample resources. Secondly, argue for the most secure choice of which kind of cipher should be used for the authentication exchange between the user and the entertainment service web portal. The entertainment service is expensive to the customer, and users are wary of the misuse of their accounts. Consider the nature of the traffic and its pattern, and the nature of the keys to use.Is it possible to encrypt both the data and the connection from beginning to end? What are the advantages of doing this? Please provide an example of a situation in which the use of encryption might be advantageous.
- To protect communication between itself and its abroad counterparts, a government agency determines that encryption is required. For this reason, it is decided at a meeting with its competitors to develop a proprietary encryption technique.Is this decision justifiable? What risks are being tolerated?Is it feasible to encrypt data at both the connection and end-to-end levels? What is the advantage of this? Provide an example of a situation in which all forms of encryption are advantageous.Is it feasible to encrypt both the data and the connection from beginning to end? What are the advantages of doing this? Please provide an example of a situation in which the use of encryption might be advantageous.
- A government department decides it needs to use encryption to protect communication between itself and its international counterparts. At a meeting with its counterparts, it is decided to develop a proprietary cryptographic algorithm for this purpose. a) Is this decision justifiable? b) What risks are being taken?Is it true that using symmetric encryption techniques comes with a set of advantages as well as a set of disadvantages? What kinds of things should be taken into account before deciding on a certain method of encryption to put into practise?
