Concerning the problem that the existing direct anonymous authentication scheme cannot achieve effectively in different domains,based on the original direct anonymous authentication scheme,in this paper a direct anonymous authentication scheme was designed.It took the certificate issuer outside the domain as a proxy,and the certificate was issued by certificate issuer outside the domain directly,which solved the privacy protection problem of trusted computing platform effectively in different trusted domains,and it had permission settings to trusted computing platform in different trust domains.Demonstrated by analysis,this new scheme meets the requirements on anonymity,unforgeability and prevention of replay attacks.Furthermore,it improves the efficiency of certification scheme.
