Encryption authentication method for power sensing equipment

Abstract

The invention discloses an encryption authentication method for power sensing equipment, relates to the field of electrical engineering science, and adopts an Internet of Things cloud service platformand a block chain management algorithm framework to realize security authentication of access of the power sensing equipment to a cloud platform through a block chain authentication and encryption algorithm capable of running on the cloud platform and an equipment end. Specifically, a power sensing equipment identity authentication architecture with a decentralization characteristic is constructed; bidirectional identity authentication between equipments and between the equipment and the platform is realized without the intervention of a trusted third party, so that the equipments can verifythe identities of each other, thereby establishing a trust relationship to realize the functions of subsequent data interaction behaviors and the like. According to the invention, the safety and reliability of electric power data acquired by the electric power sensing equipment are ensured.

Description

technical field [0001] The invention relates to the technical field of smart grids, in particular to an encryption authentication method for power sensing equipment. Background technique [0002] With the effective integration of the new generation of information technology such as the Internet of Things and the Internet with the smart grid, the traditional power grid is gradually transformed into a two-way interactive service model of the smart grid. Information and other content, so as to make reasonable arrangements for power operation and maintenance. Compared with the traditional power grid, the heterogeneous intelligent terminals of the new power grid are diversified, the network security protection boundary is ubiquitous, and the business security access requirements are diversified, which directly increases a series of security issues such as power terminal information leakage, illegal access, and loss of control. Risks increase the difficulty of security protection...

Problems solved by technology

[0006] The existing hardware and software encryption methods are essentially based on the encryption architecture centered on the remote management platform or cloud service platform. The emergence of these solutions has gradually weakened the security of these solutions; at the same time, hardware encryption devices will increase system costs and increase the complexity of system installation, deployment, and operation and maintenance; software encryption algorithms will affect the computing power and storage of power sensing terminal equipment. Higher requirements are put forward for capacity and energy consumption, so it is not suitable for the application and promotion of massive power sensing terminals
