Enhanced secure and efficient mutual authentication protocol in IoT-based energy internet using blockchain

Energy Internet (EI) has emerged as a promising paradigm for integrating various smart grid technologies through the Internet to provide reliable and sustainable energy services. However, this integration also brings new security challenges, particularly in terms of mutual authentication between various IoT devices in the EI. This paper proposes an enhanced mutual authentication protocol for IoT-based EI using blockchain technology. Our protocol builds on an existing smart grid authentication protocol and incorporates blockchain-based security mechanisms to ensure secure communication between various IoT devices. We implement our blockchain network and deploy our smart contract on Hyperledger Fabric, a popular blockchain platform. To evaluate the performance of our protocol, we use Caliper benchmarking and test its security using BAN logic and ProVerif. Our experimental results demonstrate that our protocol achieves both security and efficiency. This work contributes to securing EI using blockchain technology and demonstrates the potential of blockchain technology for mutual authentication in IoT-based EI.
