Abstract: The scheme of multi-valued pseudorandom key sequence generator based on the triple sets of bent-functions is proposed. Designed generator has a high level of cryptographic and stochastic quality and can be used in modern telecommunication systems. The full class of 3-bent-sequences is constructed and classified. The concept of the ternary algebraic normal form is introduced and the fast method for its finding is developed.

Keywords: key sequences generator, multi-valued logic, bent-function, stream encryption algorithm.
