A MODERN ADVANCED HILL CIPHER INVOLVING A PAIR OF KEYS, MODULAR ARITHMETIC ADDITION AND SUBSTITUTION

Abstract

In this investigation, we have developed a symmetric block cipher which includes iteration process, a pair of keys, modular arithmetic addition, mixing and substitution. The mixing and substitution used in each round of the iteration is strengthening the cipher significantly. The avalanche effect and cryptanalysis carried out in this analysis clearly indicate that the strength of the cipher is considerable and it can be fairly used for the security of information
