“…To achieve more practical quantum authentication, a single photon measurement has been proposed and applied in some studies [38][39][40]. In these methods, legitimate participants share information for identification before communication, and the sender, who need to identify themselves, sends photons encoded by the pre-shared information.…”

Entity authentication is crucial for ensuring secure quantum communication because the identity of the participants in a network must be confirmed before transmitting any confidential information. We propose a practical entity authentication protocol, which uses authentication qubits, for quantum key distribution (QKD) network systems. In this protocol, authentication qubits encoded with pre-shared information are generated and exchanged to verify the legitimacy of each entity. Using the authentication qubit, participants can identify each other with the same level of security as in QKD through the quantum channel. The proposed protocol can be easily integrated into existing QKD systems without additional hardware. In this study, we demonstrate the efficacy of the proposed scheme using a 1 x N QKD network system, and verify its stable operation over a deployed fiber network. In addition, we present a security analysis of the proposed entity authentication protocol and architecture.

Entity authentication is crucial for ensuring secure quantum communication as it helps confirm the identity of participants before transmitting any confidential information. We propose a practical entity authentication protocol for quantum key distribution (QKD) network systems that utilizes authentication qubits. In this protocol, authentication qubits that are encoded with pre-shared information are generated and exchanged to verify the legitimacy of each entity. By using the authentication qubit, participants can identify each other with enhanced security level through the quantum channel. The proposed protocol can be easily integrated with existing QKD systems without the need for additional hardware. In this study, we demonstrated the efficacy of the proposed scheme using a 1xN QKD network system and verified its stable operation over a deployed fiber network. Additionally, a security analysis of the proposed entity authentication protocol and architecture is provided.
