Abstract: The existent XML signature technique has two problems that it is hard to search subtle granular information and slowly to sign. In order to solve these problems, this paper proposes a transformation algorithm of abstract information based on the semantic path, in the light of constructed XML index tree. With using transformation algorithm, speed of searching information is quick. Through signing the semantic path and the information, the efficiency and flexibility of signature can be enhanced, date security and good formation of document can be guaranteed.

摘要： 针对现有的XML签名对特定细粒度信息查找困难和签名速度慢的问题，提出一种基于语义路径提取信息的变换算法，此语义路径通过构建XML索引结构得到。运用该算法查找细粒度信息方便快捷。对语义路径和信息的签名提高了XML签名的效率和灵活性，保证了数据的安全和良好的文档结构。
