Abstract

Abstract: A new certificateless threshold proxy signature scheme is presented by using certificateless public key cryptography. By analyzing the scheme in this paper, it is concluded that the scheme satisfies the security requirements of proxy signature, such as strong unforgeability, 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.

Key words: certificateless public key cryptography, certificateless signature, threshold proxy signature, bilinear pairing

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。
