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.
