Abstract：For Session Initiation Protocol (SIP) based security mechanism of IP Multimedia Subsystem(IMS), the threats and attacks on SIP were analyzed. The Identity-Based Cryptography (IBC) based lightweight security scheme for SIP was proposed, combined with Identity-Based Authenticated Key Agreement (IBAKA) and integrity of critical header fields. The security of the proposed scheme was analyzed, and its security and attack-resistance were compared with other typical schemes. The experimental results indicate that the new protocol improves greatly in security and suffers fewer threats.
