Question: For all questions assume that plaintext message length is an exact multiple of block size. 1.) This question is If the block size is 64

For all questions assume that plaintext message length is an exact multiple of block size.

1.) This question is If the block size is 64 bits, and the message X=m₁m₂ consists of 2 blocks m₁ and m₂. If message X is the tenth message to be encrypted using CBC with the same key, designated as k, what is the size of the cipher text?

2.) Same as question 1 but instead use Chained CBC instead of CBC
