Abstract

Aiming at the existing problems such as privacy exposure, data security and regulation, and high overhead in shared energy storage, this paper proposes a secure trading system for shared energy storage based on blockchain and IPFS. Blockchain is utilized to achieve decentralized energy storage transactions, ensuring transaction anonymity and immutability of transaction records. Firstly, the BF-IBE algorithm is employed to encrypt transaction records, addressing the issue of information exposure. And it introduces IPFS distributed storage for encrypted orders to improve storage and query efficiency. Secondly, it conducts decentralized and traceable supervision based on smart contracts and blockchain, resolving regulatory overhead issues, ensuring the integrity of transaction amounts, and preventing malicious competition. Thirdly, it combines smart contracts and digital signature technology for identity authentication to ensure that legitimate users modify the energy storage transmission status information and ensure data integrity. Finally, security proofs, system implementation, and experimental tests are conducted to analyze off-chain and on-chain computational efficiency and resource consumption. The experimental results demonstrate that the system is secure and efficient.

Keywords
