The security vulnerabilities in current GSM networks allow eavesdroppers to monitor entire communication between the mobile device and the base station over the air. In this thesis, a security framework for mobile communication is proposed. Within this framework, we develop a secure key exchange protocol using Elliptic Curve Diffie Hellman (ECDH). We further employ double hash chains for session key generation in order not to repeat resource-hungry ECDH operations too often and in order to provide forward and backward secrecy. We adopt this key exchange and generation protocol to short message service (SMS) and voice communication in mobile environment. As a proof of concept, we also implement our framework on Android platform. Moreover, we analyzed the performance of our framework using different mobile equipments. For the voice communication protocol, we also measure the data network performance for various places in the city.
