Abstract

The invention discloses a power distribution longitudinal encryption method and system based on quantum encryption, and the method comprises the steps: generating an absolutely safe quantum key based on a BB84 principle through employing quantum characteristics; based on a bidirectional authentication technology of a digital certificate, bidirectional identity authentication between the power distribution terminal and the power distribution master station and between the power distribution terminal and the security gateway is realized, and attack forms such as terminal identity counterfeiting and replay attack are effectively prevented; and the confidentiality and integrity of service data are ensured by using a data encryption and message authentication technology based on a symmetric cryptographic algorithm.

Description

technical field [0001] The invention relates to a vertical encryption method and system for power distribution based on quantum encryption, and belongs to the technical field of distribution network communication security. Background technique [0002] With the deepening development of smart grid and global energy Internet, the power communication network is becoming more and more open and interactive, and information security problems are also emerging. There are security risks such as forgery of identities, replay attacks, and information leakage in network communications. . In order to ensure the safe and stable operation of the power grid, discover hidden dangers in time, improve the quality and reliability of power supply, implement a distribution encryption security scheme, and meet the network security protection requirements of the distribution automation system, it has become an urgent problem to be solved in the current distribution network. The most fundamental s...
