Problem
Assume in ECBC-MAC, you are using a new block cipher (PRP_New) that uses an input block size of 10 bytes.
• Explain how Alice will use this new PRP to create a MAC for a msg of size 48 bytes.
• Explain what Bob will do when he receives the plain text and the Tag from Alice.
• Explain what will happen on both sides (i.e., Alice and Bob's side) when the message size is 60.
