本文提出了基于单控制方的可控量子网络编码方案,实现对传统量子网络编码方案中接收方的解码控制.该方案以经典XQQ(Crossing Two Qubits)协议为基础,引入可控隐形传态的控制方到网络编码模型当中,对两个接收方的解码实现控制.方案分析表明,这种新型方案实现了在没有控制方允许的情况下,即使攻击者获得了接收方全部信息也无法解码获得传输的量子信息,从而提高了量子网络中信息传输的安全性.
This paper proposes a controlled quantum network coding scheme based on single controller so as to control the decoding operation at the receivers for traditional quantum network coding schemes.This scheme is designed based on the paradigm XQQ(Crossing Two Qubits) protocol, and it can control the decoding process of two receivers simultaneously by means of introducing the controller in controlled teleportation.Scheme analyses show that without the permission of the controller, any attacker cannot decode and acquire the quantum information from the senders in this scheme, even if he can get all the information of the receivers.Thus our scheme can enhance the security of transferring quantum information in quantum networks.
