摘　　要：For the problem of security properties scale badly of the Direct anonymous attestation （DAA） scheme based symmetric bilinear pairing, a new DAA scheme based on asymmetric bilinear pairing, which gives a new practical solution to ECC-based TPM in protecting the privacy of TPM,is presented. The scheme takes on new process and framework in sign protocol, of which the TPM has only to perform three exponentiations, moreover, the signature which isn＇t knowledge of signature, is a signature of the ordinary ecliptic curve system itself. Compared to other schemes, the whole performance of the scheme is the best,and the scheme not only satisfies the same proper- ties, but also is more simple and efficient. This paper gives not only a detailed security proof of the proposed scheme which shows that the scheme meets the security require- ments of anonymity and unlinkability,but also a careful performance analysis by comparing with the existing DAA schemes.
