A Secure End-to-End Mobile Chat Scheme

Currently, mobile communications are provided convenient methods to explore and communicate with each other people. A multitude of services have converged on the smartphone platform, and potentially the most notable is social networking. Thus, the electronic Mobile Chat (MC) plays a very important role in the social networking. With the increasingly growing reliance on Mobile Chat System (MCS) in one hand, and the growing number of vulnerabilities and attacks on the other hand, there is an increasingly demand for the security solutions. Despite of the critical role of MCS in the typical Internet mobile user´s life, electronic MC services are not so secure. Therefore, the secure End-to-End Mobile Chat (SE2E-MC) scheme is proposed to be one of the suitable solutions. The basic framework for SE2E-MC scheme and its associated requirements are also designed in this paper. The proposal is implemented to provide mutual authentication and prevent the password guessing attack and the undetectable on-line password guessing attack. Finally, the scheme is a password-based authentication and key agreement (AKA) having easy remembered property.
