Automatic quantum key charging method and system adapting to electric power services

Abstract

The invention discloses an automatic quantum key charging method and system adapting to electric power services. Quantum keys are divided into a quantum authentication key, a quantum encryption key and a quantum updating key according to a deployment structure for electric power service main station convergence and electric power service terminal access; the quantum authentication key is used foridentity authentication during communication interaction; the quantum encryption key is used for encryption and decryption of data during the communication interaction; and the quantum updating key isused to encrypt and decrypt a new quantum key in the communication interaction when used to update the quantum authentication key and the quantum encryption key and / or the quantum updating key. The quantum updating key updates the quantum authentication, encryption and / or updating keys, thereby realizing automatic charging and updating of the 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
