Abstract:

As the traditional software-based SIP security schemes are vulnerable to embezzlement,deception and invasion,a dual authentication framework combined with the trusted computing technology is proposed for endpoint system and user identity. Then,a new SIP security scheme for Internet multimedia communication is presented,which takes advantage of the trusted platform module and the direct anonymous attestation algorithm to design a new registration sub-protocol for improving the security of multimedia communication systems. Moreover,the security of the registration sub-protocol is verified by using the provable security model,and the characteristics of the whole scheme are finally analyzed.

Key words: Internet multimedia communication, security, session initiation protocol, trusted computing
