摘要
给出了 2种基于身份的类环签名方案 ,在该方案中签名者能够代表他属于的集合 ,但是 ,验证者却不能识别哪个成员的签名 .对于一个攻击者而言 ,即使他拥有所有成员的密钥 ,他也不能决定是哪个成员签名 ,从而实现了无条件的匿名性 .
This paper presents two ID-based analogous ring signature schemes in which any user can sign on behalf of the set to which he belongs, but a verifier can't tell which member actually produced the digital signature. For an attacker, even if he had known all the secret signing keys, he couldn't have identified the actual signer. In this paper our proposed schemes realize unconditional anonymity.
