Abstract

The invention discloses a two-side authentication method for a power system, and the method is used for a wireless communication network. The method comprises the steps that a first communication node generates a first public and private key pair as a secret key pair, and generates a part of second secret keys; a second communication node generates a second public key, and generates the second secret key according to the part of second secret keys, wherein the second secret key pair serves as the secret key of the second communication node. Therefore, the method improves the safety of the system.

Description

technical field [0001] The invention relates to the technical field of security authentication, in particular to a two-party authentication method oriented to an electric power system. Background technique [0002] The application of wireless communication technology and encryption technology in the power grid provides technical support for system state analysis and auxiliary decision-making, making it possible for the power grid to heal itself. The security of the smart grid requires that both the physical and network levels of the system have strong security features and robustness, that is, it can resist attacks to the greatest extent or recover quickly after an attack. The security strategy of the smart grid will include deterrence, prevention, detection, and response to minimize and mitigate the impact on the grid and economic development. [0003] The wireless communication network (wireless communication network, WSN) is an important part of the bottom layer of the s...
