Cryptography Technique with Modular Multiplication Block Cipher and Playfair Cipher

Authors(2) :-Robbi Rahim, Ali Ikhwan

There are many data security techniques like a cryptography, there are many algorithm like a MMB (Modular Multiplication Block Cipher) and Playfair Cipher. MMB operates using 128-bit plaintext, but it also uses 32-bit subblock MMB text (x0, x1, x2, x3) and 32-bit key subblock (k0, k1, k2, k3) and then the fundamental of this algorithm is determined by a multiplication modulo operation 232-1. Different from MMB, playfair cipher is a diagram substitution cipher which takes two letter from message and replace with two another pair letter, this paper combines playfair cipher as a key substitution and messages in plaintext to be encrypted with algorithms MMB, this combination is expected to increase the security level of messages
