一种基于身份的不可传递环签密算法

An Identity-based Non-Transferable Ring Signcryption

在诸如匿名电子举报这类数字签名应用中,不仅需要确保被签名信息的机密性和签名者的身份模糊性,同时还需要确保签名的不可传递性。论文针对这类应用提出了一种基于身份的不可传递环签密算法,该算法通过环签密实现被签名信息的机密性和签名者身份的模糊性,并通过有机融合验证者签密伪造算法实现了签名的不可传递性。

In some applications of signature, such as anonymous e-prosecution system, the identity of the signer should be ambiguous, and the non-transferability of the signature should be guaranteed. This the paper proposes an identity based non-transferable signcryption scheme, the scheme builds up a signcyption algorithm, thus ensuring the confidentiality of the signature and the ambiguity of the signer＇s identity. It also designs a signcryption forging algorithm for designated verifier to guarantee the non-transferability of the scheme.
