摘　　要：针对传统电力系统用户数据隐私泄露及安全性较低的问题,提出了一种基于区块链的去中心化数据聚合模型。该模型应用领导人选举算法从住宅区选择一个智能电表作为参与区块链网络的挖掘节点,并使用Merkle哈希树对住宅区的智能电表进行安全认证和数据聚合。应用Paillier加密、短签名和SHA-256技术,在确保区块链数据透明的同时,实现多重隐私保护,可以有效抵御敌手如重放攻击、篡改等威胁。实验阶段,以计算开销和通信开销对所提模型进行验证。结果表明,与其他模型相比,所提基于区块链的去中心化数据聚合模型在计算开销和通信开销均表现优异。In order to solve the problems of user data privacy leakage and low security of traditional power system users,a decentralized data aggregation model based on blockchain was proposed.The model applied the leader election algorithm to select a smart meter from the residential area as the mining node to participate in the blockchain network,and used the Merkle hash tree to perform security authentication and data aggregation on the smart meter in the residential area.Paillier encryption,short signature,and SHA-256 technology were used to ensure the transparency of blockchain data while achieving multiple privacy protections,which can effectively defend against threats such as replay attacks and tampering.In the experimental stage,the proposed model was verified by calculating the overhead and communication overhead.The results showed that compared with other models,the proposed blockchain-based decentralized data aggregation model performed well in both computational overhead and communication overhead.
