一个新的不含双线性对的无证书签名方案

摘要

基于无证书密码体制提出了一种不合双线性对运算的无证书签名方案，该方案能够追踪恶意的私钥生成中心的恶意行为，达到了Girauh的安全等级3，具有不可伪造性．%A new certificateless signature scheme without pairing is proposed based on Certificateless Public- Key Cryptography. The new scheme can trace PKG＇ s malicious behavior, and reaches trust level 3 defined by Gifault, thus realizing real non-repudiation.
