摘要: 该文提出了一个新的无源光网络PON组成模型。利用该模型设计了一个具有身份认证功能的高效量子密钥分配方案，以满足无源光网络中光线路终端对光网络单元的身份认证和两者间的相互量子密钥分配，以及实现光虚拟专用网内部光网络单元间的量子密钥分配。安全性分析和实验方案表明了该协议的绝对安全性和可行性。将共享密钥作为通信双方的会话密钥，对内部传输数据进行加密，最终实现量子虚拟专用网。

Abstract: A novel Passive Optical Network (PON) model is proposed. By exploiting this architecture, an efficient Quantum Key Distribution (QKD) protocol with Quantum Identity Authentication (QIA) is designed. In this scheme, both the QIA and QKD between optical line terminal and optical network units in this PON are implemented. Also, the QKD is implemented between each two optical network units in the same optical virtual private network with the simple operations of optical line terminal. The security proofs and the proposed experimental scheme show this protocol is feasible and absolutely secure. Quantum virtual private network can be ultimately realized by using the conversation key generated by QKD protocol to encrypt the intra-communication data. -
