Advanced Ciphering Algorithm Based On Playfair Cipher

Osman Mohammed Dafa Alla

Abstract


In this paper an advanced ciphering algorithm based on the conventional Playfair ciphering is
presented. This advanced ciphering algorithm is achieved through ciphering the plaintext n times
with n random keys. The advanced algorithm has been designed using Matlab program. The
computer simulation tests for the conventional Playfair ciphering and the advanced algorithm
has been done. Analysis of the results has been carried out. These results show that the
advanced ciphering algorithm is very complicated and is strong enough against nearly all attacks
compared with the conventional Playfair ciphering.

Keywords
