BIOINSPIRED ALGORITHMS FOR SOLVING CRYPTANALYSIS

004.056.55

The problem is considered of cryptanalysis based on new models of artificial intelligence – bioinspired methods. The review of the handiworks devoted to the solution of a problem of cryptanalysis of classical cryptographic methods, including methods of cryptanalysis of symmetric codes of shifts, classical and block codes of replacement is provided, the technique of representation of an individual, prevention of illegal decisions, and also the description of function of fitness (Jacobsen's function) are given. Also «the algorithm of an ant» and algorithm of «a colony of bees» for realization of cryptanalysis of permutable codes, and also for realization of cryptanalysis of asymmetric algorithms of enciphering on the basis of the solution of numbertheoretic problems of cryptography along with experimental results are investigated. The received experimental results testify to possibility of application of the bioinspired methods for cryptanalysis realization
