With the advancement of quantum communication infrastructure, especially the completion of the “Quantum Beijing-Shanghai Trunk Line” and the launch of the Mozi quantum satellite, more and more industries have begun to incorporate quantum cryptography into business systems. However, it brought trouble to the key management of the original business system. In this paper, in order to solve problem of managing quantum and classical keys, an unified management architecture of quantum and classical keys is designed, which contains four key components: Power vertical encryption & authentication gateway, classic encryption device, QKD device, and unified key management center. All of these four components cooperate with each other to form a complete and efficient integrated key management system, which effectively solves the problem that the current power system cannot realize the quantum key management.
