摘要

基于身份的密码体制、利用双线性对映射特性提出了一种前向安全的门限代理签名方案,方案具有前向安全的特性。引用双线性缩短签名长度、效率更高;基于签名者的身份信息使得签名方案具有很好的可追踪性和抗抵赖性;由于不需要可信中心的支持派发密钥,显著增强了方案的可适用范围。通过安全性分析证明了方案具有强壮性和不可伪造性的特点,并且通过实际应用于PCI—E密码卡,证明了方案具有一定的适用价值。
        A forward secure threshold proxy signature scheme by utilizing bilinear pairings mapping characteristics and identity-based cryptography is proposed. The proposed scheme is characterized by forward security. Through employing the bilinear pairings mapping,it shortens the length of signature and improves signature efficiency. Since signer-based identity information makes the presented scheme has good traceability and non-repudiation. So,applicable range of the scheme is obviously strengthened without supporting of trusted center sending secret key. According to security analysis,it is proved that,this scheme is robust and unforgeable and applied in the PCI—E encryption card,its practical value is demonstrated.
