Quantum Key Interaction Mechanism for Power Communication Access Network
Zhiping Yan, Qiang Zhang, Yanbin Song, Jianan Yuan · 2018
With the increase of cyber-attacks, the risks of information leakage, falsification and forgery, and bypass control are intensified, and attackers can attack the primary station circuitously through the terminal, resulting in a wider range of security threats. Quantum cryptography has a higher level of security than traditional cryptography. In this paper, a quantum cryptosystem suitable for power communication access network is proposed, and various practical quantum communication devices are designed, and proposes a key reading mode between the service terminal and the quantum key mobile storage device, an interface protocol between the service terminal device and the quantum key mobile storage device, and a key management method applicable to the terminal for the service of the electric service. The application of quantum communication technology to power systems plays a vital role in ensuring the safe, stable and efficient operation of the power grid.
