C = Cipher text Write the symbolic logic for the 3DES decryption. [ Your answer should go here] Describe the logic in a few sentences. 20 points. [ Your answer should go here] 3. Assuming an initial implementation of your encryption system was done using DES. What issues would need to be addressed if you decide to upgrade to the 3DES algorithm? There are several issues to consider. You should identify at least 4 issues and place them in a numbered list. While there may be better algorithms than 3DES to upgrade to the problem is not concerned with that. The problem is bounded by the stated parameters of moving from DES to 3DES. There are numerous issues to consider moving from DES to 3DES and these are what you need to focus on. 10 points. [ Your answer should go here] 4. Your manager is considering purchasing a message authentication system. She is considering 3 different systems. One system uses MD5 hashing, another uses SHA2 hashing and the other system uses a brand new hashing algorithm called VSH (Very Smooth Hash). You have been asked to prepare an executive summary (i.e. clear and concise) that describes the attributes of each algorithm and the pros and cons. You should consider reviewing each algorithm along the same primary dimensions and then focus on differentiating factors where appropriate.
