%X In order to fit with the distributed and decentralized characteristics of P2PSIP, this paper proposed an authentication and key agreement mechanism based on certificateless public-key cryptography, and discussed its correctness, security and performance. This scheme satisfied the common admissive security demands in key agreement and reduced computation costs for not using bilinear pairings. As compared to the existing schemes, the new scheme maintains high security and has higher efficiency.
