摘要: 代理签名方案能够委托签名权利,环签名方案能够实现匿名签名,由此提出一种基于身份的代理环签名方案。通过将原始签名人扩展到环中,使验证者只能确定原始签名人及代理签名人来自某个环,无法获知委托人以及签名人的具体身份。理论分析证明该方案具有正确性、不可伪造性、匿名性和可区分性。

关键词: 基于身份的签名, 代理环签名, 双线性对, 匿名性, 不可伪造性

Abstract: Signature right can be delegated in proxy signatures. Ring signatures can achieve signing in an anonymous way. An ID-based proxy ring signature scheme is proposed based on the advantages of proxy signature and ring signature. In this scheme, not only the proxy signers are members of a ring, but also the original signers are extended into a ring, so the verifier can only be sure the rings which the original signer and the proxy signer belong to, but can not disclose the identity of the principal and the signer. Theoretical analysis shows that the scheme satisfies the properties of verifiability, unforgeability, anonymity and distinguishability.

Key words: ID-based signature, proxy ring signature, bilinear pairings, anonymity, unforgeability
