摘要: 结合代理签名和盲签名的特点,提出了一种无证书的代理盲签名方案。新方案采用了无证书公钥密码体制,解决了基于证书签名方案的证书管理问题和基于身份签名方案的密钥托管问题。分析表明,该方案不仅满足代理盲签名所要求的所有性质,而且方案中密钥生成中心(KGC)与用户间不再需要可信的安全通道,更加适合实际应用。

Abstract: A certificateless proxy blind signature scheme is presented,which satisfies the security properties of both proxy signature scheme and blind signature scheme.Based on certificateless public cryptosystem,it avoids the using of certificate in certificate-based signature scheme and removes key escrow in ID-based signature scheme.Analysis shows that the proposed scheme can satisfy all the required properties of a proxy blind signature,and it does not need the confidential channel between KGC and users.
