Problems solved by technology
Experiments have shown that quantum communication signals transmitted by optical fibers are almost completely absorbed after two hundred kilometers. Therefore, if only optical fiber transmission is used to realize long-distance quantum communication, multiple safe and reliable signal relay stations must be established. will greatly increase the cost of communication

The invention discloses a satellite-ground integrated quantum key distribution system suitable for a power system, and relates to the technical field of quantum communication. The network comprises anoptical fiber secret key distribution layer, a wireless secret key distribution layer and a satellite secret key distribution layer, wherein the satellite secret key distribution layer performs secret key negotiation based on a quantum satellite and a satellite ground station to generate a quantum secret key; the optical fiber key distribution layer performs key negotiation based on a quantum keygeneration terminal with a QKD function and a key management machine to generate a quantum key; and the wireless key distribution layer is used for distributing the quantum key to the power service terminal without optical fiber coverage based on the quantum key wireless distribution server, the quantum key charging machine, the quantum TF card and the quantum Ukey. According to the invention, multistage secret key distribution is realized, an autonomously selected space is provided for different electric power services, the problem that the secret key cannot be distributed due to wide distribution range and long transmission distance of the electric power service terminals is solved, and the overall flexibility and economy of quantum secret key distribution are fully improved.
Description
technical field [0001] The invention discloses a satellite-ground integrated quantum key distribution system suitable for electric power systems, and belongs to the technical field of quantum secret communication. Background technique [0002] Quantum secure communication technology has developed rapidly with its unique key security distribution mechanism, and is gradually moving towards commercial use. The absolute security of quantum secret communication has been strictly proved in principle, which can solve the security problem of encrypted data transmission. Compared with classical communication methods, quantum secure communication is unbreakable, and any operation that attempts to steal information will be discovered immediately.
