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...

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...
