| 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 couldnt have identified the actual signer .In this paper our proposed schemes realize unconditional anonymity . |

| Keywords: | analogous ring signature identity unconditional security |
