The analysis of symmetric cryptographic algorithms of data from the point of view of a possibility of their polymorphic implementation

The conducted researches, the opportunities of use of program polymorphism for protection of key elements of cryptographic algorithms of the symmetric encoding against unauthorized reconstruction directed to study by results of measurement and the analysis of dynamics of consuming of power in the course of execution of these algorithms on microcontrollers and smart cards, and also development of methods of implementation of polymorphism with their specification for GOST 28.147-89 standardized in Ukraine and the international standard of new generation of Rijndael. The method of implementation of polymorphism at the level of processed units in combination with polymorphism of program implementation of processing of one unit is considered.
