Abstract

Voice over Internet Protocol (VoIP) over wireless mesh networks (WMNs) is becoming more and more popular due to its significant cost advantage, higher flexibility and wide coverage. One of the most basic requirements of VoIP is that it must provide privacy and security protection for VoIP clients. Unfortunately, little effort is spent on this area. In this paper, we focus on the privacy security of session initiation protocol (SIP) and propose a privacy-aware SIP called PA-SIP to enhance the VoIP privacy security. PA-SIP extends the SIP and applies a subjective logic based reputation mechanism to detect and isolate the insider malicious nodes. Finally, we analyze the PA-SIP in terms of security and performance.
