Prospects for the application of many-valued logic functions in cryptography

Abstract

The paper considers development of cryptographic methods based on the principles of many-valued logic. The results concerning the construction of block and stream cryptographic algorithms based on functions of many-valued logic are presented. The synergy of the principles of many-valued logic and the variable fragmentation of the block made it possible to construct an effective block symmetric cryptographic algorithm. The results of computational experiments confirm its high cryptographic quality and easily scalable number of protection levels. As shown by experiments, the principles of many-valued logic are an excellent basis for the construction of gamma generators (the basis of stream ciphers), which are based on the use of triple sets of ternary bent-sequences. The paper outlines the scope of the tasks, the solution of which is necessary for the further development in this direction of cryptography.
