Voice call transmissions on cellular networks are not end-to-end secure and thus, attacks like call tracing, modification etc by an adversary is easily feasible, that is, any adversary Eve, can trace the call, and can intercept the voice, which is transmitted over an unsecured medium from a user (Alice) to another user (Bob) through mobile phones. Thus, it's not safe to private talk on the mobile phones. In this paper, we propose a scheme, which provides entire security between valid end users over the security protection provided by the network system. A common secret key is pre-negotiated between end users (many such schemes are available) to initiate the communication. We present a global construction of our proposed protocol. In addition to this, we also discuss the security proofs of our proposed protocol.
