摘　　要：研究可信计算平台的匿名认证方案,分析现有方案的优缺点,利用零知识证明思想,提出一个新的可信计算平台的匿名认证方案。新方案中TPM平台向验证者匿名认证其真实合法性,无需可信第三方的参与。与其他方案相比,该方案的认证效率更高,且在强RSA假设和判定性Diffie-Hellman假设及随机预言模型下满足不可伪造性、匿名性和撤销性。The anonymous authentication schemes for Trusted Computing Platform（TCP） is studied in this paper, the advantages and disadvantages of the subsistent authentication schemes for TCP are analyzed. A new anonymous authentication scheme for TCP is proposed by using the method of zero-knowledge proof. The validity of a TPM platform is proved anonymously, and there is no trusted third party to participate in the authentication schemes. The new scheme has higher efficiency than others and satisfies forgery-resistance, anonymity and revocation under strong RSA assumption and Diffie-Hellman assumption in the random model.
