摘要
零知识证明的量子身份认证是由一个绝对公正的第三方CA主持的协议.协议的实现是基于远程态制备,量子辅助克隆的量子操控手段.在认证过程中,只有CA知道量子身份证的信息,认证参与方Alice和Bob在不知道量子身份证的信息的基础上可完成认证工作.提出了如何提高认证成功概率的方法.协议由量子力学原理保证,有绝对的安全性.
A theoretical scheme for zero-knowledge proof quantum identity authentication is proposed by the absolutely impartial third party CA, which has been realized based on remote state preparation and assisted cloning controlled means. In the process of identification, only CA knows the information of quantum identity card and the first party Alice and the second party Bob can accomplish the quantum identity authentication without knowing it. We discuss the probability of accomplishing this job. The security of this scheme is unconditional and it is guaranteed by quantum mechanism.
