Improving Privacy-Preserving Techniques for Smart Grid using Lattice-based Cryptography

Saleh Darzi, Bahareh Akhbari, Hassan Khodaiemehr

TL;DR

The LPM2DA scheme is introduced, utilizing lattice-based encryption and signatures for secure data aggregation, ensuring privacy, integrity, and authentication, and enabling statistical analysis while preserving user privacy.

Abstract

Advancements in communication and information tech birthed the Smart Grid, optimizing energy and data transmission. Yet, user privacy is at risk due to frequent data collection. Existing privacy schemes face vulnerability with quantum machines. To tackle this, the LPM2DA scheme is introduced, utilizing lattice-based encryption and signatures for secure data aggregation. It ensures privacy, integrity, and authentication, enabling statistical analysis while preserving user privacy. Traditional aggregation schemes suffer from weak network models and centralization issues. Enter SPDBlock, a blockchain-based solution ensuring privacy, integrity, and resistance to attacks. It detects and prosecutes malicious entities while efficiently handling multi-dimensional data transmission. Through distributed decryption and secret sharing, only valid data can be decrypted with minimal involvement from smart meters. Performance tests reveal SPDBlock's superiority in communication and computational efficiency over traditional schemes.
