Application of XML Digital Signature in the Exchange of Electronic Documents

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.
