集成电子签章功能的公文流转系统的实现

摘要

It investigates the technology of electronic seal based on PKI and implements electronic seal controls based on ActiveX technologies oriented Office documents. These ActiveX controls implement identity authentication based on USBKey. Achieve content of signature document by VBA and ensure the integrity of documents by digital signatures and verification. It also develops a document circulation system with electronic seal oriented Web, in which user can add electronic seal during the document circulation to ensure the integrity of documents and non-repudiation of signature, so that the security of the document circulation system is improved.%为了在安全性要求较高的应用中使用公文流转系统,保证公文在流转过程中的完整性和签署者的不可否认性,论文研究了基于PKI的电子签章技术,实现了基于ActiveX技术的面向Office的电子签章控件.该控件采用USBKey技术实现身份认证,利用VBA提取Office文档内容,采用数字签名与验证技术保证文档的完整性.基于实现的电子签章控件,开发子面向Web的集成电子签章功能的公文流转系统,用户可以在公文流转过程中,加盖电子签章,保证了公文在流转过程中的完整性和签署者的不可否认性,从而提高了公文流转系统的安全性.
