A block cipher consists of two paired algorithms, one for encryption, E, and the other for decryption, D. Both algorithms accept two inputs: an input block of size n bits and a key of size k bits; and both yield an n-bit output block.The decryption algorithm D is defined to be the inverse function of encryption, i.e., D = E −1.More formally, a block cipher is …
