An efficient anonymous authentication scheme for blockchain assisted and fog-enabled smart grid

The growing integration of blockchain and fog computing with Smart Grid (SG) technologies highlights the need for strong security protocols, dependable communication channels, and sensitive user data protection. In order to meet the unique needs of SG, this research paper presents a novel and effective anonymous authentication scheme enhanced by fog computing and blockchain. The suggested scheme makes use of blockchain's decentralized structure to strengthen security protocols and ensure user privacy and anonymity within the SG ecosystem. Through the combination of fog computing's low latency benefits and blockchain's immutability, the suggested scheme creates a robust framework for secure authentication. The suggested approach gives considerable weight to reducing computational overhead and optimizing user identity privacy. Through comprehensive analysis, the study highlights the scheme's efficiency concerning authentication speed, resource utilization, and resilience against potential attacks. These results offer an important remedy for the ever-changing landscape of energy management systems and substantially advance the development of safe and privacy-preserving SG architectures.
