Anonymous Energy Trading Scheme for Virtual Power Plant Based on Blockchain

Abstract

This paper delves into the critical challenge of establishing a secure, private, and efficient energy trading system for virtual power plants. This paper introduces a comprehensive system model and formally defines security requirements. This paper provides an anonymous energy trading scheme employing cryptographic techniques, such as accountable ring signatures, multi-signatures and blockchain technology. Users gain the ability to confidentially negotiate energy prices, fostering a secure and private environment for the intricate process of energy trading. Subsequently, this paper conducts a rigorous security analysis and performance evaluation, aligning with the stringent security and privacy requirements. The findings affirm the effectiveness of the proposed scheme.
