A Method to Implement Direct Anonymous Attestation

HE GE

Abstract: We propose an efficient anonymous authentication scheme which might be deployed in the setting of trusted computing platform. Our construction implements features such as total anonymity, variable anonymity, and rogue TPM tagging. The new scheme is significantly simpler, and more efficient than the current solution that has been adopted in the standard specification. We have proved the new scheme is secure under the strong RSA assumption, and the decisional Diffie-Hellman assumption.
