Application of modular computing technology to nonlinear encryption in cryptographic systems of informational security

In the present paper, we deal with the methodology of nonlinear encryption on the basis of parallel modular computing structures. The use of the minimal redundant modular number system and the interval-modular form of representation of an integer number defined by its modular code creates the computer-arithmetical basis of a cryptographic procedure under consideration. The proposed encryption algorithm is based on the index method of realization of the modular multiplicative operations.
