Problems solved by technology

[0004] Based on this, the inventors of the present application found that in the prior art, the terminal devices in a station area use the same quantum key for data encryption and decryption, which has low security
To improve security and meet the requirements of terminal devices in a station area using different quantum keys for data encryption and decryption, it is necessary to increase the amount of key generation. However, the current encryption machine storage limit and the quantum key distribution Restrictions, unable to meet the needs of a large number of keys required by power distribution terminals

Abstract

The invention discloses a method and system for distributing quantum keys to terminals in a station area, the station area includes a plurality of blocks, and the method includes: determining the optimal quantity of quantum key distribution for each block ; Send a plurality of root keys to each terminal in the block, the number of which is equal to the optimal quantum key distribution number of the block to which the terminal belongs; and the root key received by each terminal pair Calculate according to a preset algorithm to obtain respective terminal keys, where each terminal key is different. The method and system for distributing quantum keys to terminals in the station area provided by this embodiment can realize the secure encrypted transmission of power distribution business data, realize the effective use of quantum keys, improve security and meet the requirements of power distribution and consumption. The need for a large number of keys required by the terminal.

Description

technical field [0001] The present invention relates to distribution of quantum keys, in particular to a method and system for distributing quantum keys to terminals in a station area. Background technique [0002] With the construction of smart grid and the continuous development of terminal technology, the security and confidentiality requirements of terminal systems are also getting higher and higher. Due to its unmeasurable and non-cloning principles, quantum keys have higher security and have gradually replaced traditional keys in smart grids. [0003] In the smart grid, the master station side of the existing scheme generates a quantum key through a quantum key generation device and stores it in the cipher machine of the master station device. The master station uses the quantum key in the cipher machine to encrypt the data, and sends the encrypted data to the terminal, or uses the quantum key in the cipher machine to decrypt the received data. On the terminal side, ...
