不需消息保密的盲代理签名方案

提出了一个不需要消息保密的盲代理签名方案,代理签名人的身份除对原始签名人外是保密的,只有指定接收者才能够验证代理签名的有效性,但无法确定代理签名人的身份,出现争议时指定接收者可以通过原始签名人揭示代理签名人的真实身份.以该方案为基础,还构造了一个高效的共享验证签名方案.

Scheme of Blind Proxy Signature Without Message Secrecy

A blind proxy signature without message secrecy is proposed. The new scheme can protect the proxy signer's privacy against the other third parties except the original signer, only the designed receiver can validate the proxy signature, but the designed verifier cannot confirm the identity of the proxy signer. The designed verifier can unveil the identity of the proxy signer via the original signer when the dispute exists. Based on the proposed scheme, a novel efficient threshold shared verification signature scheme is constructed.
