Web32) be a secure (deterministic) block cipher with 32-bits key size and 32-bits message size. We want to use this cipher to build a new (deterministic) block cipher (E 64;D 64) that will encrypt 64-bits messages under 64-bits keys. We consider the following encryption algorithm. To encrypt a message M under a key K, we split M into two parts M 1 ... WebWhat.
