Abstract

Trusted computing group developed two solutions to realize remote attestation between platforms, but both of them have drawbacks. Privacy CA defined by trusted computing group needs to be highly available and may collude with verifier to trace user´s transactions. direct anonymous attestation proposed in trusted platform module specification v1.2 is not efficient because it adopts many exponential operations and the Issuer may collude with verifier, too. In this paper, we propose a remote anonymous attestation scheme with an improved privacy CA. The Privacy CA issues an anonymous attribute credential for a trusted computing platform and doesn´t need to be involved in all attestations. It is also not able to leak the privacy of users. The proposed scheme is high efficient and fulfills the requirements of anonymous credential system very well.
