Development of the model of protected cross-border information interaction

Abstract

This article investigates a proposed model of cross-border exchange and information security in the cross-border interaction in the integration system. A structural scheme of protected cross-border information exchange is proposed. Cross-border interaction of sides for information exchange in the integrated system is provided by the creation and use of the integration segment and national segments. The main tasks of a trusted third party are formulated. The model of sides’ interaction scheme of the integration system using the integration gateway is presented. In this paper, a model of modified nonconventional digital signature system based on the scheme of the Digital Signature Algorithm and nonpositional polynomial number systems (NPNs) are described. Application of NPNs allows creating effective cryptographic systems of high reliability, which enables the confidentiality, authentication, integrity of stored and transmitted information.
