Abstract: In a network of participants who wish to communicate or access multimedia service using voice over IP (VoIP), session initiation protocol (SIP) is used. SIP exists in the application layer for signalling to initiate, update and terminate the sessions. Before initiating the session, the security necessitates authentication of participating entities. A mutual authentication mechanism is required for SIP in order to establish a secure session between the two entities. In password-based authentication, a user needs to remember his username and password in order to have a session with another user. In this paper, we have proposed an efficient smart card-based mutual authentication scheme (CP-MASIP) for SIP which is based on Chebyshev chaotic map. In addition to providing security against various known attacks, our scheme provides user anonymity which is a very important security parameter in the present world. The scheme has been analysed using BAN logic and informal security analysis.
