中文摘要：
提出将标准模型下基于1-MOMSDH假设的短群签名方案作用于DAA协议，该协议基于Fiat—Shamir启发式设计思想，完成了协议知识签名的数学构造，实现了非交互式零知识证明到知识签名的转化．具有签名长度短、运行效率高及标准模型下可证安全等特性，提高了现有协议的安全性，同时兼顾协议执行效率．
英文摘要：
We deisgn a DAA scheme based on Short Group Signature on 1-MOMSDH assumption. On the basis of Fiat-Shamir heuristic theory, the signature of knowledge and realization of the transformation from non-interactive zero knowledge proof to signature of knowledge are introduced. Because of its short signature, high efficiency and provable security in Standard Model, the security of DAA is increased while its efficiency is also guaranteed.
