An Identity-based Non-Transferable Ring Signcryption
Xiong Yan · Information Security and Communications Privacy · 2007
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.
