A Scalable Multi-hash Remote Attestation Approach for Trusted Transaction

Trusted transaction is becoming more and more important as malicious user or agent inside the network may compromise the upcoming transaction. Trusted Computing mutual remote attestation mechanism is a relative new approach to overcome this problem. But limited computation capability of TPM device on the sever side is an obvious bottleneck of scalable performance. by introducing a novel high efficient remote attestation mechanism tailored specially for server platform, we greatly increase the scalability of server platform. Experimental measurement and theoretical analysis show that handling multiple transaction requests only increases the average dealing time a constant increment, which takes great efficiency advantages comparing with existing linear approaches.
