A secure approach for SMS in GSM network

Abstract

The Short Message Service (SMS) is one of very popular kind of superior and well-tried services with a global availability in GSM networks. This paper deals with an SMS security for mobile communication. The transmission of an SMS in GSM network is not secure; therefore it is desirable to secure SMS by additional encryption. A proposed approach, based on encryption and digital signature efficiently embeds the confidentiality, integrity, authentication, and non-repudiation in the SMS messages. In the next part, there is the description of design and implementation of the application, which encrypts SMS by DES, Triple DES, AES and Blowfish algorithms and finally signs SMS by DSA or RSA algorithm respectively. At the end, we described attacks on secured SMS and future extension of the application. Copyright 2012 ACM.
