Mixing of (Prime-Matrix) to duplicate the complexity of Ciphering (Play Fair Mixed R.S.A.)

Abstract

In this research mixing between two methods(Traditional), the first will be matrix technique from playfair method and the other is (prime) R.S.A. Technique for pair of characters , which take the rules of these two algorithms and mixed it in one algorithms called "Prime-Matrix" Algorithm, which we make it in this research, and then we compare between the two methods especially the letters will never repeat in the cipher text also the prime numbers are so many to hack.
