Security of mobile VoIP [articol]

Abstract

The rapid growth of computing, Internet and telecommunications systems have created a broad range of ways to communicate and access information. Voice over Internet Protocol is a solution that transports voice traffic over a data network as an alternative to the classic telephony. This paper addresses the issues of VoIP security and mobility through the integration of robust security features into a lightweight VoIP protocol that is tailored for mobile devices. A theoretical approach is realized with the development of a software prototype whose security and mobility properties are analyzed.
