Abstract

Session Initiation Protocol (SIP) plays an important role in VoIP, peer-to-peer (P2P) network has been used as virtual server in SIP, and however, it is difficult to authenticate with each other and to exchange session key because of missing central authority (CA). In this paper, the security threats in Peer-to-Peer SIP (P2PSIP) architecture are analyzed, then a new P2PSIP authenticated key exchange mechanism based on Self-Generated-Certificate Public Key Encryption scheme (SGC-PKE) is proposed, which assures the Integrity, Confidentiality and Non-repudiation of messages in P2PSIP network, and overcomes some shortcomings from traditional public key cryptography (PKC) system.
