%X The existing direct anonymous attestation scheme achieves anonymous attestation using group signature,identity managed, certificate system technology and so on, which has the defect being slow implementation of the efficiency and poor safety. The computing speed of the new XTR public key cryptosystem is fast, and its safety is well.Based on the XTR public key cryptosystem, using zero-knowledge proof, this article improved the original direct anonymous attestation scheme. Demonstrated by analyzing, compared with the original mechanism, the security and implementation of this new scheme have been improved greatly.
