The SRTP/ZRTP security mechanism provides a secure channel for VoIP (Voice-over-IP) traffic transmission. This paper examines the use of TCG remote attestation technique to improve the security of SRTP/ZRTP channel technology. We first generalize the security properties which a trust channel technique should have. Then we propose a trusted SRTP/ZRTP channel technique and apply model checker SPIN to...
With the increasing popularity of VoIP (Voice-over-IP), the integrity of associated communication endpoints becomes a significant security issue. TCG remote attestation mechanism can be used to evaluate the platform state of remote endpoints. However, there are no protocols and extensions that aim to integrate remote attestation with the existing secure mechanisms for SIP-based VoIP transmission by...
