一个无证书的环签名方案

A Certificateless Ring Signature Scheme

无证书公钥密码体制简化了传统公钥体制负担过重的密钥管理问题,在不失基于身份的公钥体制其密钥管理简单的前提下克服了其所固有的密钥托管缺陷.基于无证书公钥体制提出了一个高效的环签名方案,可以实现签名者的无条件匿名性,且能有效抵制来自密钥生成中心的伪造攻击,适用于对安全性能要求较高且匿名的场合.

Certificateless public key cryptography reduces the difficult problem of key management in traditional public key cryptography, it also eliminates the key-escrow problem of identity-based cryptography and also preserves all of its advantages. A the lowest calculating time ring signature scheme is proposed, it can resist forgery attacks from the secret key generation center and can meet with the requirements of unconditional anonymity of signers, so it is suitable to the application of high security and anonymity.
