VoIPS: VoIP secure encryption VoIP solution

Abstract

VoIP technology allows voice messages transmitted through the network, but it also encounters information security threats such as packet sniffering and authentication. In this research we propose an integrated algorithm - VoIPS (VoIP Secure). It conduct a secured VoIP communication which afforded confidentiality and message authentication. Furthermore, side-effect to performance is trival and able to eliminate the risk of well-known replay attack which used on VoIP system. According to our simulation experiments, the proposed system can be created to construct a secure VoIP communication system. A hardware prototype is created to verify the proposed system which practically feasible. © 2011 Springer-Verlag.
