Let's say that you receive a ciphertext that was encrypted with a b-bit permutation and is nb-bits in length. (That is you receive an n-block ciphertext.) But, you did not receive an IV or nonce (if one was needed) along with the ciphertext. For each of the following modes indicate how many ciphertext blocks you could correctly decrypt into plaintext blocks without knowing an IV or nonce. ECB: choose your answer... CBC: : choose your answer... CTR: choose your answer... e your answer... choose your answer... n o ht n-1 w 1 choose your
