Novel Ultra-Lightweight Leakage-Resilient Blockchain-Assisted Key Exchange Protocol for Resource-Constrained Smart Meters in Smart Grid
- Published
- Record updated
Summary
This paper shows that a leakage-resilient authenticated key exchange protocol for smart grid, proposed by Cheng et al., is vulnerable to offline password-guessing and key compromise impersonation (KCI) attacks and lacks perfect forward secrecy (PFS). The authors propose a decentralized ultra-lightweight AKE protocol between neighborhood service providers (NSPs) and smart metering devices (SMDs) that uses the public Solana blockchain for transparency and key revocation. They report 24% and 98% improvements in communication and computational overheads.
