| 摘 要： | 随着各种网上办公系统的应用，公文传输，网上审批等操作的安全性已经越来越引起人们的重视，数字签名的开发与研究为这种新的网上办公系统提供了安全有效的解决方案。介绍利用MD5算法与RSA算法实现公文传输的数字签名。防止公文在传输中被他人修改或顶替，从而确保公文的原始有效性和真实性。利用发送方与接受方之间比较严密的应答协议，克服了单纯利用数字签名带来的弊端，比较适用于当前的B／S架构的OA产品。提供了安全可靠的MD5算法与RSA算法，并指出两者单独使用的不足。

| Abstract: | Under the trend of official business work on Internet,the security of official document transmission,Internet authentication and so on is drawing more and more attentions.The D&R of digital signature provides safe and efficient measures for official business on Internet.How to use MD5 and RSA computing methods to realize digital signature in official document transmission is introduced.The modifying and replacing are prevented by other people during the transmission of official document to ensure the validity and authen-ticity ofdocuments.By taking advantage of advanced response protocolbetween sender and receiver,the shortage of pure digital signature is avoided.It is suitable for current B/S frame OA products.The paper not only provides safe and reliable computing methods MD5 and RSA but also point out the shortage of separate usage. |
