 Title: Genetic Algorithm for Finding the Key’s Length and Cryptanalysis of the Permutation Cipher Authors: Gorodilov, AlekseyMorozenko, Vladimir Keywords: CryptographyCryptanalysisBlock Permutation CipherGenetic AlgorithmData Encryption Issue Date: 2008 Publisher: Institute of Information Theories and Applications FOI ITHEA Abstract: In this article we discuss a possibility to use genetic algorithms in cryptanalysis. We developed and described the genetic algorithm for finding the secret key of a block permutation cipher. In this case key is a permutation of some first natural numbers. Our algorithm finds the exact key’s length and the key with controlled accuracy. Evaluation of conducted experiment’s results shows that the almost automatic cryptanalysis is possible.
