摘要： 对基于可信计算中DAA协议的一种匿名多重签名方案进行了安全分析，指出其不能抵杭签名伪造攻击，因此是不安全的。分析了这一安全缺陷产生的原因，并给出改进的多重签名方案。改进方案在每个签名者提交的部分签名中加入了DAA证书信息，使得最终生成的多重签名不可被伪造。它在保留了原方案的主要优点的前提下，克服了其安全缺陷。

Abstract: Aimed at an anonymous multi-signature scheme based on DAA technology for trusted computing, this paper analyzed its security and demonstrates that it is vulnerable against signature forgery attack. The reasons why such security flaws exist in the scheme was investigated and an improved version was proposed. The improved scheme associates every signer's DAA certificate with its partial signature. The unforgcability of the final multi-signature is guaranteed because the attackers can not forge a l)八A certificate. The new scheme not only retains the major advantages but also overcomes the security flaws of the original scheme.
Key words: Cryptography, Trusted computing, DAA protocol, Multi-signature
