A quantum key automatic filling method and system adapted to electric power business

Abstract

The invention discloses a quantum key automatic charging method and system adapted to electric power business, complies with the deployment architecture of power business master station convergence and power business terminal access, and divides quantum key into quantum authentication key, quantum encryption key key and quantum update key, the quantum authentication key is used for identity authentication during communication interaction, the quantum encryption key is used for encryption and decryption of data during communication interaction, and the quantum update key is used to update the quantum authentication key and quantum encryption key And / or when the quantum key is updated, the encryption and decryption of the new quantum key in the communication interaction. Quantum authentication, encryption and / or updating keys are updated through quantum updating keys, so as to realize automatic filling and updating of quantum keys.

Description

technical field [0001] The invention relates to a quantum key automatic filling method and system adapted to electric power services, belonging to the technical fields of quantum mechanics and information science. Background technique [0002] At present, the important business of the power system is mainly encrypted and transmitted through the optical fiber private network and the national commercial encryption algorithm, and its security mainly depends on the privacy of the key and the complexity of the calculation. However, with the development of attack technology and the enhancement of human computing power, non-destructive eavesdropping and camouflage attack methods for optical cables have appeared. Showing an exponential decline, the risk of the traditional security system being cracked is increasing day by day. [0003] Quantum key distribution is based on the basic principles of quantum mechanics, which guarantees in principle that once there is an eavesdropping, i...

Problems solved by technology

However, due to the characteristics of photons that cannot be cloned or divided, quantum channels can only use bare optical fibers as the transmission medium, and cannot be split, amplified, or regenerated in the middle, which takes up a lot of bare optical fiber resources

At the same time, the current power communication network uses various communication methods such as optical fiber, wireless, and power line carrier, and a large number of methods such as optical amplifiers and electrical relays are used to extend the transmission distance. It is difficult to meet the above requirements, which limits quantum security to a certain extent. Practical promotion of communication technology in power system
