Abstract (Summary)

The Session Initiation Protocol (SIP) is an application-layer control protocol that can establish, modify, and terminate multimedia sessions (conferences) such as Internet telephony calls and it is defined in the RFC3261. SIP is vulnerable to significant risks and vulnerabilities as the signaling is done over open and highly insecure Internet and SIP also offers user mobility. The massive deployment of Voice over Internet Protocol (VoiP) had raised the importance of the security and more precisely of the underlying signaling protocol SIP.

In this thesis, we have studied the various security risks to SIP and various security mechanisms used with SIP to mitigate those risks. We have also evaluated the impact on performance of SIP registrar and proxy servers due to the overheads imposed by SIP authentication and use of Transport Layer Security (TLS) with SIP. The performance impact is evaluated using an experimental test-bed comprising of an Open Source SIP Server (OpenSIPS) and an open source SIP performance (SIPp) bench-marking tool. We have also profiled the system costs in TLS using the OProfile utility of Linux.
