摘要
针对电子公文在存储和传输中的安全认证需求,对电子印章系统设计中的关键问题进行了研究。综合数字签名技术和双重数字水印技术的优点,基于现有CA系统提出一种电子印章系统构建方案,实现了对电子公文的内容认证和盖章实体的身份认证,同时继承了传统印章的形象性和权威性。然后基于Word开发原型系统,并构造典型攻击进行实例测试。实验结果表明,该系统能够满足电子公文认证的安全需求。
To achieve safety certification for electronic documents in the process of storage and transmission,the key problem in the design of the electronic seal system is studied.Combined with the digital signature and dual digital watermarking technology,a new electronic seal system solution based on the CA system is proposed.This authentication mechanism can realize the content authentication and entity authentication,in the meanwhile inherit the visualization and authoritativeness from traditional seal.At last,a prototype of electronic seal system based on Word is implemented,and the simulation on the typical attack against the electronic document proves the validity of the model proposed.
