Describe the different modes of block cipher. [5]
A block cipher encrypts a fixed-size block of plaintext into a block of ciphertext using a key. However, most real-world messages are longer than a single block, so different modes of operation define how to apply the block cipher repeatedly to encrypt longer messages. The five standard modes of ...
