Abstract:

Following the developmental trend of the next-generation-network protocols, we analyze the characteristics of the P2P-SIP network which combines the SIP protocol and P2P networks. Considering its strengths and weaknesses, we design a certificateless anonymous protocol based on elliptic curve algorithms for P2P-SIP, which can be applied in IPv6 network. We prove the proposed protocol under the CK security model and do security analysis on the protocol. The security analysis demonstrates that the proposed protocol has the following security attributes: mutual authentication, excellent forward secrecy, anonymity, known key security, and key compromise impersonation. The proposed protocol can also effectively resist the known-key attack, Man-in-the-middle attack, SYBIL attack, and some other attacks. We compare our protocol with previous protocols and show that our protocol has more security attributes and more effective than the previous protocols.
