| 摘 要： | 结合无证书的密码体制，提出一个新的无证书的门限代理签名方案。经分析表明，方案满足代理签名的安全要求，具有强不可伪造性、强不可否认性、强可识别性、可区分性、防止滥用等性质，且门限值由原始签名人确定，还能抵抗鲁荣波等人提出的攻击。

| Abstract: | A new certificateless threshold proxy signature scheme is presented by using certificateless public key cryptography. By ana- lyzing the scheme in this paper, it is concluded that the scheme satisfes the security requirements of proxy signature, such as strong un- forgeability, strong nonrepudiation, strong identifiability, distinguishability, misuse prevention. The threshold value is determined by original signer. Moreover, it can resist the attack proposed by Lu Rongbo et al. |
