Developing a system for text-messages protection

Abstract

This article addresses the issue of SMS-messages protection from unauthorized access and malicious software. The intruder model's structure and main security threats are presented. The authors tell about the requirements for protective systems of this kind, examine the main threats to the security of information and describe the system development tools such as protecting messages using the RSA algorithm, using ELGamal algorithm and using an algorithm based on elliptic curves. The performance results and effectiveness of the proposed ideas are provided. The implementation can be performed directly on mobile subscribers in the form of a software product, or as additional functional software of a virtual operator.
