摘要
目前电力系统中普遍采用 MIS实现办公自动化 ,完成文档的生成、确认、签发、传递、存档等工作。当前的 MIS都是采用简单的用户名 /口令机制实现对用户的身份认证 ,不能提供实质上的安全签名服务。采用基于公钥密码算法的数字签名可以充当个人在网络空间“身份证”的角色 ,能够很好地解决目前 MIS存在的敏感文档签名问题。文中介绍了密码算法的基本原理 ,给出了数字签名的解决方案。
Currently MIS has been widely applied in power system to realize office automation that includes creating, confirm ing,signing,delivering and archiving of documents.Now MIS generally identifies a user via a sim ple user/ password mechanism,but is unable to supply secure signature services in essence.A digital signature based on public key algorithms is illustrated,which can be regarded as an identification card in cyberspace and can properly solve the signature problem of sensitive documents in power system .The principles of cryptographic algorithm are analysed,and the plan of solving signature problem of sensitive documents with digital signature is proposed in detail.
