Quantum Key Mobile Distribution Method, System, Terminals, and Storage Medium for Communication System Encryption in Power System

Abstract—In this paper, mobile distribution method, system, terminal, and storage medium based on quantum key (QK) are introduced for communication system encryption in electric power system, which mainly includes following steps. Firstly, the QK management platform (QKMP) can initialize the embedded QK mobile storage device (QKMSD). Secondly, if the QKMSD is initialized, the QKMP will finish the distribution of QKMSD to users, in the meantime, users finish the registration and activation by binding the user identity with the device. Thirdly, the QK charger (QKC), as well as the QKMP, accomplishes the verification to QKMSD, respectively. If the verification is succeeded, the QKC will obtain the QK from original QKMSD, and QK is written-in the QKMSD, finishing the QK charging. Final experimental results demonstrate that, by QKMSD with QK charging authority, secure distribution of QK in the non-fiber communication environment can be implemented.
