摘要
针对共享储能存在隐私暴露、数据安全及监管、开销大等问题,文章提出基于区块链和IPFS的共享储能安全交易系统。利用区块链实现去中心化储能交易,保证交易匿名性及交易记录不可篡改。首先采用BF-IBE算法加密交易记录,解决信息暴露的问题。引入IPFS分布式存储加密订单,提高存储查询效率。其次基于智能合约和区块链,进行去中心化可追溯监管,解决监管开销问题,确保交易金额完整,防止恶意竞争。再次结合智能合约和数字签名技术进行身份认证,确保合法用户修改储能输送状态信息,保证数据完整。最后进行安全性证明、系统实现与实验测试,分析链下、链上计算效率和资源消耗,实验结果表明系统安全高效。
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.
