基于IBC数字签名机制在电厂SIS中的应用

IBC-based Digital Signature Mechanism Applied in Power Plant SIS

基于身份的密码系统使得用户的公钥能够通过用户的身份信息直接计算出来,不需要保存每个用户的公钥证书,避免了使用证书带来的存储和管理开销的问题,简化了基于证书的密码系统繁琐的密钥管理过程,并对基于身份的公钥系统和基于证书的公钥系统进行了比较和讨论。最后构建了基于双线性对和基于身份的数字签名解决方案,并对方案的安全性和效率作了分析。

Based on identity-based cryptosystem,the user＇s public key can be calculated directly through the user＇s identity infor- mation,thus each user＇s public key certificate does not need to be saved.This method avoids the storage and management cost problems caused by the use of certificate,and simplifies the complex certificate-based key management process.The i- dentity-based public key system and certificate-based public key systems are discussed and compared in this paper.Eventually,bilinear pairing and identity-based digital signature solutions are constructed.
