摘 要: 代理盲签名在电子支付系统、电子投票系统、移动代理系统和网络安全等方面有着广泛的应用。基于Einstein-Padolsky-Rosen(EPR)对的纠缠相干性和可控量子隐形传态,提出了一种量子代理弱盲签名方案。不同于经典的基于计算复杂性的代理盲签名方案,本方案利用量子力学的物理特性来实现消息盲化、签名及验证,保证了消息所有者的匿名性和方案的无条件安全性。 Proxy blind signature was applied to the electronic paying system, electronic voting system, mobile agent system, security of internet, et al. A quantum proxy weak blind signature scheme is presented based on the correlation of Einstein-Padolsky-Rosen (EPR) pairs and controlled teleportation. Comparing the traditional proxy blind signature schemes based on computing complexity, the scheme uses the physical characteristics of quantum mechanics to implement message blinding, signature and verification, so it could guarantee not only the unconditionally security of the scheme but also anonymity of the message owner.
