摘要
在研究RSA数字签名算法和XML的基础上,结合RSA算法的安全性和XML文档的结构优势,提出一种基于XML文档划分的多重签名方案。此方案利用Xpath语言访问节点数据的相应规则,把XML文档划分成与不同签名者对应的子文档,并建立Xpath规则与不同签名者的对应关系。签名者只需要对相应的Xpath规则进行签名即可,这样既保证了各签名者对其负责的子文档签名,又提高了签名的效率和灵活性。
By utilizing the structure predominance of XML document and the security of RSA algorithm, proposes a multi-signature scheme based on XML document. In this scheme, uses the rule of Xpath language to transform an XML document into subdocument, and estabhshes corresponding relationships of each subdocument and the different signer. The participant signers sign only on the rule of XPath corresponding the subdoeument that they are responsible for. Consequently, the scheme improves the efficiency and the flexibility of signs.
