Yang, Bo; Zhu, William; Dai, Yuanshun; Yang, Laurence T. and Ma, Jianhua. The Eighth IEEE International Conference on Dependable, Autonomic and Secure Computing : proceedings : Chengdu, China : 12-14 December 2009, p.78-83
Voice service is vulnerable to a number of attacks that can compromise the confidentiality, integrity and authenticity of voice communication. This paper describes the design of communication protocols for securing SIP based VOIP communication. It presents the architectural principles involved and the overall security solution comprising the design of secure extensions to SIP messages. Finally it evaluates the performance of the proposed scheme and presents some results.
