| 摘 要： | Trusted computing （TC） technology is brought out by trusted computing group （TCG） to make computing as safe and reliable as people expect. Attestation is one main function specified by TCG, which is the means by which a trusted computer assures a remote computer whose platform is not tampered with. There are two protocols that implement attestation without disclosing the platform＇s real identity, which are Privacy CA-based protocol and direct anonymous attestation （DAA） protocol. However, in the first protocol the privacy CA is the bottleneck and the platform＇s identity will be disclosed if the privacy CA is compromise, while DAA protocol can do profiling when dealing with rogue hardware device. In this paper, we propose a DAA-extended new approach to ensure full anonymous attestation that can not only detect a rogue TPM, but also reveal rogue TPM＇s real identity.

| Abstract: | Trusted computing (TC) technology is brought out by trusted computing group (TCG) to make computing as safe and reliable as
people expect. Attestation is one main function specified by TCG, which is the means by which a trusted computer assures a
remote computer whose platform is not tampered with. There are two protocols that implement attestation without disclosing
the platform’s real identity, which are Privacy CA-based protocol and direct anonymous attestation (DAA) protocol. However,
in the first protocol the privacy CA is the bottleneck and the platform’s identity will be disclosed if the privacy CA is
compromise, while DAA protocol can do profiling when dealing with rogue hardware device. In this paper, we propose a DAA-extended
new approach to ensure full anonymous attestation that can not only detect a rogue TPM, but also reveal rogue TPM’s real identity.
