基于XML的电子公文多重签名算法

随着电子公文应用的发展，多重签名算法的安全性成为研究热点。本文针对XML格式的电文公文多重数字签名的特点，提出了一种安全的多重数字签名算法。该算法在多重签名的产生阶段加入新的计算公式来生成多个签名，签名收集者使用算法就可以确定那一个签名者的签名被纂改。通过和Eric Jui-Lin Lu的签名方案比较，证明了该算法是可行和有效的。

SCHEME ON MULTI-SIGNATURE FOR ELECTRONIC DOCUMENTS BASED XML

With the growth of electronic documents, the security of signature algorithm becomes hotpot of research. Aiming at the features of multi-signature for electronic documents, this paper proposes a security algorithm basing on extensible markup language(XML) documents. During the signatures producing, the proposed method provides some new formulas with irreversible arguments. Signature collectors can verify the signature by the formulas. At the mean time, they can find the signatures which are falsified. To compare this algorithm with Eric Jui-Lin Lu, the proposed scheme is efficient and feasible.
