基于PKI的电子印章系统

本文将数字签名技术应用于电子印章，设计了一套基于PKI的电子印章系统。这套电子印章系统采用XML数据格式、原始文档、印章图片和落款等盖章信息在盖章文件中分开存放，支持多次盖章和同时盖章。通过客户端浏览器插件和Office插件，可以在浏览器和Office中完成盖章、验证、浏览等功能。最后，本文给出了基于B／S结构的电子印章系统结构，并以甲、乙双方在同一文档上盖章为例，介绍了盖章、验证和再盖章的过程。

An Electric Seal System Based on Public Key Infrastructure

An electric seal system based on PKI and digital signature is set up in this paper. The file data format of sealed document is XML. The original sealed document iseal picture and inscriber etc are saved in different element of sealed document- Seal,verify and view scaled document can be done in Office and Internet Explore through software plug in. The structure of electric seal system based on Browser/Server is recommended and a example of two person seal on one document is referred to show the process of seal,verify and seal again.
