Session Initiation Protocol (SIP) is an application-layer signaling and control protocol for creating, modifying and terminating sessions including Internet telephone calls, multimedia distribution and multimedia conferences. Flexible, extensible and open, SIP has a complete security mechanism that allows security of both media and signaling. SIP RFC recommends the use of TLS or DTLS (Datagram TLS defined in RFC 4347) to provide an adequate level of protection against attacks. However, missing from these protocols is a way to perform non-repudiation service. In this paper we propose to modify some header fields in the SIP messages in order to allow them to perform non-repudiation service over TLS. This modification provides the User Agents (UAs) the ability to sign their SIP messages using certificates such as X.509.
