Abstract

SIP (Session Initiation Protocol) application is used in the field of multimedia communications more and more widely as the core signaling control protocol in NGN (Next Generation Network). The current authentication mechanism in SIP is a digest authentication mechanism based on HTTP, which is vulnerable to off-line password guessing attack, server spoofing attack, etc. In order to overcome the above disadvantages, this paper proposes a new mutual authentication, which is based on the chaotic theory. The chaotic sequence’s characteristics of randomness and ergodicity can not only generate nonce for the digest authentication, but also provide a key for the session. Moreover, we should expand some header fields of SIP to meet the needs of the new authentication mechanism.
