Research and application of anonymous identity authentication between TPMs
TPM匿名认证机制的研究与应用

This paper analyzed the implementation of anonymity in the TPM authentication schemes.By modifying the direct anonymous attestation(DAA)scheme,proposed a design scheme for trusted on-line service systems called TOSS.Comparing to the traditional systems,this system is based on user levels.As it supports anonymous access,hierarchical service and peri- odic control,TOSS provides better security and service evolution function.
