Modified Hill Cipher with Key Dependent Permutation and Circular Rotation

V.U.K. Sastry and V. Janaki

Abstract

In this study, we have modified the Hill cipher, by including a permutation and circular rotation into the cipher. Here both the permutation and the rotation depend upon the key. From the cryptanalysis and the avalanche effect, discussed in this study, we notice that the strength of the cipher is significant.
