基于双线性对的身份数字签名方案

利用双线性对技术提出了一种基于身份的签名方案,该方案以用户的身份信息,如电子邮箱地址、IP地址、电话号码等作为用户公钥,从而降低了建立和管理公钥基础设施的代价,同时用户密钥采用密钥生成中心和用户协商生成,避免了密钥分发中心得到用户密钥而伪造签名。

Signature scheme based on bilinear pairs

An identity-based signature scheme is proposed by using bilinear pairs technology.The scheme uses user＇s identity information as public key such as email address,IP address,telephone number so that it erases the cost of forming and managing public key infrastructure and avoids the problem of user private generating center generating forgery signature by key distributing center cooperating with user to generate user＇s private key.
