一种基于数字签名的网页原始性鉴别方法*

针对传统网页原始性鉴别方法效率低、安全性差等不足,基于数字签名技术提出了一种改进方案.确认管理员身份无误后,通过数字签名保证上传网页真实、可靠;Web服务器用自己的密钥对接收的文件进行数字签名;用户申请访问网页时,服务器通过验证数字签名鉴别网页的原始性.实验结果表明该方法是可行的,具有安全性好、准确率高等特点,为网页防窜改系统的设计提供了一种新方案.

New Method of Aboriginality Identifying for Webpage Based on Digital Signature

In order to avoid the tampered Webpages being browsed,a new method based on digital signature was proposed.After ensuring the identity of administrators,the Webpage files during uploading,those accepted by the Web server were being processed with digital signatures,and the original digital signatures were safely stored in the Web server memory.Before a Webpage was being browsed,its aboriginality was verified through validating digital signature.Experiment results show that the technique is feasible,and has the features of high precision and security.Thus,it provides a good solution to the design of Webpage tamper-proofing system.
