The paper considers development of cryptographic methods based on
the principles of many-valued logic. The results concerning the construction of
block and stream crypto 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 crypto 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 article outlines the scope of the tasks, the solution of which is necessary for
the further development in this direction in cryptography.
