WebWhen the time comes to send a message x 2f0;1g128 to Bob, Alice considers two ways of doing so. She can use the key as a one time pad, sending Bob k x. Alternatively, she can use AES to encrypt x. Recall that AES is a 128-bit block cipher which can use a 128-bit key, so in this case she would encrypt xas a single block and send Bob AES k(x). WebLP1) Bob has to send a secret code S to his boss.
