一种基于无证书的门限盲代理盲签名方案

A Certificateless-based Threshold Blind Proxy Blind Signature Scheme

在无证书的公钥密码体制下,提出了一个基于无证书的门限盲代理盲签名方案。将代理签名、盲签名还有门限签名有机的结合,既解决了代理者权利过大的问题,又保护了代理者的隐私。该方案满足正确性、强不可否认性、不可伪造性、盲性等性质。

A certificateless-based threshold blind proxy blind signature scheme was presented by using certificateless public key cryptography. The combination of proxy signature and blind signature and threshold signature was used in this paper, which can solve the problem of the proxy signer＇ s au- thority was too big, and protect the proxy signer＇ s privacy, the scheme satisfies accuracy, strong nonre- pudiation, unforgeability, blind, et al.
