Applying Genetic Algorithms for Searching Key-Space of Polyalphabetic Substitution Ciphers

: In this paper the Cryptanalysis of polyalphabetic by applying Genetic algorithm is presented. The applicability of Genetic algorithms for searching the key space of encryption scheme is studied. In Vigenere cipher, guessing the key size is done by applying Genetic Algorithm. The frequency analysis is used as an essential factor in objective function.
