Assignment: AES Encryption This assignment familiarizes you with AES encryption. We are given a 128-bit message M 2C58FD04C2D8DB1928E11849B997044E (in hexadecimal) and a 128-bit cipher-key K 8EF8553B444EC546F3AAAF56287AB13 (also in hexadecimal). Using AES encryption scheme discussed in class, find the following values. Write your answer in hexadecimal (capital letter) without inserting any space between hexadecimal digits (for example, write "9F2C", not "9f2c" or "9F 2C") 1. In Round 1 of the encryption process, what...

Problem 1 Consider the 3-bit block cipher in slide 8-18. Suppose the plaintext is 101101101. If CBC is used with initial vector 110, what will be the resulting ciphertext? Show work, not just the final answer. Problem 2 Consider RSA with public key (n, e) and private key (n, d) where n = 35, e = 5, and d = 29. What is the encryption of m = 34? What is the decryption of c = 34? Show calculations, not...

What is the key difference between an array and a symbol table? Assume you have a bunch of objects containing information about different SER classes and need to store their data somewhere. You could use their course number as a key and then store them into either an array or symbol table - which would be better if you wanted to quickly print out all of the classes? Explain. Show...
