Smart grid environment using block chain-based key agreements

Abstract

Smart grids are one of the main difficulties to ensuring system security is the access verify the huge amount of terminal devices and intelligent gateways. Therefore, a new key management method that is more efficient, secure, and cheap to compute is required for smart grids. However, the majority of existing research is unable to strike a compromise between computational burden and security. To eliminate these advantages, a novel Secure Key Exchange (SKE) mechanism for low computational cost and data security in blockchain-based smart grids has been proposed in this research. In addition to including a blockchain-based key exchange, the proposed SKE architecture also includes layers for management, power, transmission, intelligent gateway, and user (UL). Transmitter substations, power plants, dispatching centers, and transmission stations have all added layers to blockchain technology. The proposed SKE technique consists of four stages: joining, departing using the Diffie Hellman algorithm, authentication, establishment, registration and initialization. The MATLAB simulator has been updated to include the recommended method. The effectiveness of the recommended approach has been assessed in relation to particular metrics like computation and security analysis. In comparison to DPPDA, MAS, and DBACP-IoTSG approaches, the proposed SKE protocol extends the lowest computational cost by 2.1 %, 4.5 %, and 13.1 %, and is more secure, accordingly.
