An Identity-based Non-transferable Ring Signature
Fuyou Miao · Jisuanji fangzhen · 2009
Some digital signature applications in Network Environment,e.g. an anonymous e-impeachment,has the requirement of guaranteeing both the signer-ambiguity and non-transferability,but most of the current signature schemes can not fully meet such requirements. The paper proposes a new scheme called Identity-based Non-transferability Ring Signature Scheme,in which a special hash function from bilinear pairing is constructed. Thus the scheme satisfies the above applications requirements. Formal analysis shows that the scheme is signer-ambiguous,non-transferable and non-forgeable in Random Oracle Model.
