XML数字签名在电子公文交换中的应用

Application of XML Digital Signature in the Exchange of Electronic Documents

本文探讨了XML数字签名的基本原理和语法格式以及XML数字签名与传统数字签名方法相比具备的优势,研究了其实现原理,然后在.NET平台上实现了的XML数字签名,并将其运用到实际的办公自动化系统中,实现电子公文交换的安全性、完整性、不可否认性,而且由于XML数字签名自身的优势,使得数字签名更加灵活、实用。

Electronic documents exchange is an important thing in E-government construction. It improves the translation and the handling speed of electronic documents which are translated through network. However, because of the diversity, opening and interconnection of network＇s connection way, electronic documents are easily attacked by hackers and hostile software. It results in the fact that the data of electronic documents may be filched, counterfeited, modified and disavowed. So the electronic documents security is the most important thing. XML has been recorded as network data exchanging and publishing standard. It has been applied in several programming environment of data exchange between application software, such as E-business and E-government. The paper discusses basic theory and syntax format of XML and the advantage of XML digital signature comparing with traditional digital signature, researches its realization theory then realizes XML digital signature on NET framework, also applies it to actual OA. It realizes the security, integrality, impossible disavowal of electronic documents interchange, meanwhile makes the digital signature more flexible and practical.
