Cryptanalysis of Simplified Data Encryption Standard Using Genetic Algorithm

Abstract

Cryptanalysis of cipher text using evolutionary algorithm has gained much interest in the last decade. In this paper, cryptanalysis of SDES has been performed using Genetic Algorithm with Ring Crossover operator. Cryptography has been prone to many attacks but the scope of this paper is limited only to the cipher text attack. Different combinations of keys are generated using the Genetic Algorithm and hence it is concluded that Genetic Algorithm is a better approach than the Brute Force for analyzing SDES.
