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。

关键词: 类环签名, 身份, 无条件的安全性

Abstract:

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 .

Key words: analogous ring signature, identity, unconditional security
