Message modular interpretation for information protection systems

Fundamental principles of modular technology interpretation posts in information protection systems (IPS) are presented in the article. The computer arithmetic base of these technologies is the modular arithmetic (MA). In particular, given the mathematical formalization of the principle of the modular massages’ interpretation, as well as the necessary and sufficient conditions for its feasibility by a two-stage scheme of composition within the table-summatory computing MA-structure. The proposed technology allows to minimize difficulty and the execution time of the basic procedures of a position-modular IPS interface of this class. The coding and decoding algorithms that contain only logic and assignment operation are synthesized. In the traditional positional interpretation of data in IPS of modular type the forward and reverse code conversion takes time O (ns) modular operations each (n - length of position code of messages, and s- length of modular code of messages).
