摘要: 提出一种可追踪签名者的环签密方案。在利用环签名实现匿名签密通信的基础上,在环签名中附加一些与环成员相关的信息,必要时可通过环中所有节点的协作追踪签名者的真实身份。环签名中不存在可信中心,使方案更适合在移动自组网中实现可控匿名通信。理论分析证明了该方案的正确性、匿名性和安全性。

Abstract: This paper proposes a signer-traceable ring signcryption scheme. The program achieves anonymous signcryption communication by using ring signatures and attaching some additional information about ring members in ring signatures. If necessary, through the coordination of all nodes, the procedure can track the true identity of the signer. There is no center node in the ring signature, so it is more suitable for mobile Ad Hoc network of controllable anonymous communication. The correctness, pseudonym and security of the new scheme are proved by theory analysis.

Key words: bilinear pairing, ring signature, anonymous communication, identity tracing, signcryption
