可验证其他成员是非签名者的环签名

Ring signature with proving other members are not real signer

环签名方案是签名者在不泄露身份的情况下生成的一个签名。验证者可以验证签名确实是环成员生成的,但不能确定哪一个成员是真实的签名者。于是提出了可否定的环签名方案,利用这一方案,签名者可以向接受者证明其他成员并不是真实的签名人,但同时并不暴露自己的真实身份。

A ring signature scheme enables a signer to produce a signature without realing identity. A verifer can verify that the ring signature was made by a ring member, but cannot identify the real signer. This paper presents a deniable ring signature scheme, the signer can prove that other member is not the real signer, but not expose himself.
