Symmetric Authenticated Encryption (AE)
Explain intuition behind authenticated encryption modes, and fully describe one mode of your choice with block diagrams. You can use PowerPoint drawing tools to draw your block diagrams. If you strictly wish to avoid drawing, you can also express modes of operations with proper algorithmic descriptions. For example, one can express ECB mode as simple as C_i ß E(K,M_i), i=1,…,n, where n is the number of message blocks. You can seek from various resources how to express your authenticated encryption modes in this way.
