无证书多重代理多重盲签名方案

为了提高盲签名的安全性和实用性,结合无证书公钥密码体制、多重代理多重签名和盲签名,首次提出了一个无证书多重代理多重盲签名方案。在该方案中,需要所有的原始签名者合作才能完成代理授权,同时只有所有的代理签名者合作才能产生多重代理多重盲签名。该方案解决了多个代理签名者代表多个原始签名者进行盲签名的问题。经分析得知,方案同时具有多重代理多重签名和盲签名所需的安全特性。

Certificateless Multi-proxy Blind Multi-signature Scheme

In order to improve the security and practicality of blind signature,this paper introduces a certificateless multi-proxy blind multisignature scheme by adopting certificateless cryptography,multi-proxy multi-signature and blind signature.In this scheme,the original signers can cooperatively finish proxy-delegatation process,and the proxy signers can cooperatively generate multi-proxy blind multi-signature.The scheme solves how to generate blind signature while multiple proxy signers sign the message on beha...
