提出了一种量子代理签名方案,利用量子力学中Einstein-Podolsky-Rosen(EPR)的纠缠特性并结合经典编码方法来实现对量子比特串的签名和验证.在本方案中,原始签名人可以将自己的签名权委托给代理签名人,而量子密钥分配和一次一密保证了新方案的无条件安全性.研究表明新方案满足不可伪造性、不可否认性和可追踪性.

This paper presented a quantum proxy signature scheme which allowed users to obtain the signature and verify of a quantum bit sequence by using the entanglement characteristic of the EPR state and the way of classical encode.In this new scheme,the original signer could delegate his or her signing rights to proxy signer.Guaranteed the unconditionally security of this scheme by quantum key distribution and one time pad.Results show that this new scheme satisfy non-counterfeit,non-disavowal and traceability.
