摘　　要：为了有效解决现有的直接匿名认证方案中认证效率低、成员加入过程复杂的问题,本文在直接匿名认证方案中引入短签名方法,设计出改进的应用于成员加入与签名阶段的直接匿名认证机制,从而提出一种基于短签名的直接匿名认证方案DAA-ss,DAA-ss方案简化了成员证书的签发过程,减少了签名阶段的计算量,实现了认证效率的提升。DAA-ss具有可证明的安全性,实现用户的身份隐私。In order to effectively solve the problem of low authentication efficiency and complicated member joining process in the existing direct anonymous attestation scheme, this paper introduces a short signature scheme in the direct anonymous attestation scheme, and designs an improved direct anonymous attestation scheme applied to the member join and sign phase. Therefore, a direct anonymous attestation scheme DAA-ss based on short signature is proposed. The DAA-ss scheme simplifies the issuance process of member certificates, reduces the calculation amount in the sign phase, and improves the authentication efficiency. DAA-ss has provable security and achieve the identity of user.
