Lightweight R-LWE-based privacy preservation scheme for smart grid network

Abstract

Privacy preservation is one of the important research challenges in IoT applications. In one such IoT application; smart grid network, billing information and energy profiling information of the customer may be collected, aggregated, and forwarded to control centre for further analytics. Based on the research findings, traditional public key cryptography is not secured against quantum attacks. Our study is motivated by the recent developments in the lattice-cryptography schemes. This paper presents a lightweight R-LWE lattice-cryptography-based scheme to sign and encrypt message traffic in smart grid. Security analysis suggests that proposed scheme preserves the privacy of customer. Performance analysis shows that proposed scheme cause less communication overhead as compared to traditional public key cryptography yet maintain parallel with NTRU-based scheme and outperforms both formats of public key cryptography in regards to computation overhead.
