Abstract: Combining proxy blind signature with certificateless signature scheme,a certificateless proxy blind signature scheme is proposed.This scheme can overcome the problem of the certificate management in the certificate-based public key cryptosystem and the inherent key escrow problem in the identity-based public key crytosystem.Finally,an analysis of the scheme’s security is presented.The scheme satisfies the security properties of blind proxy signature scheme and proxy blind signature scheme,and it has strong enforceability.

Key words: certificateless, proxy blind signature, bilinear pairings

摘要: 将代理盲签名和无证书签名方案结合,充分利用二者的优势,提出一种无证书代理盲签名方案。使签名避免了基于证书密码系统的证书管理问题和基于身份的密钥托管问题。并对其安全性给予分析,分析结果表明,该方案同时具有代理盲签名的各项安全性质以及强不可伪造性。
