ASSESSMENT OF EFFICIENCY AND COMPARATIVE CHARACTERISTICS OF THE COMBINED BIOINSPIRED CRYPTANALYSIS ALGORITHMS

Is devoted to the solution of a relevant task of cryptanalysis with use of new model of optimizing strategy – the combined bioinspired algorithms. The article deals with the problem of determining the effectiveness of combined bioinspired algorithms used in recent years to solve a wide range of combinatorial optimization scientific and technical problems and combining different or similar algorithms, but with different values of the parameters in which the advantages of one algorithm can compensate for the shortcomings of another. Application of the combined bioinspired algorithms (a genetic algorithm, algorithms of ant and bee colonies) for realization of cryptanalysis of permutation ciphers is considered. Determination of the complexity of the algorithms is carried out on the basis of the pseudo-code, which represents the implementation of the basic operations of cryptanalysis methods.
