EEE-GSM: End-to-end encryption scheme over GSM system

Abstract

GSM system is widely used by hundreds of millions of people. In fact there is no encryption scheme provides the reasonable security level (user-to-user encryption), it's just provide the Air-interface encryption i.e. between the mobile station and the base station. Furthermore, there are other wireless links are vulnerable to attacks. It is therefore of great importance to provide reasonable security techniques to ensure the privacy of the mobile users especially circuit switching-based services, as well as prevent unauthorized use of the service. In this paper, a new approach is proposed to provide end-to-end encryption for the GSM system (EEE-GSM). This is achieved by using CL-PKC with some modifications and follow some assumptions in GSM system architecture in order to make the scheme compliant to the GSM cellular system. However, the proposed scheme not only efficient due to end-to-end security, but can also provide a secure system against IMSI catcher, man-in-the-middle, and replay attacks.
