【摘要】 针对区块链存储容量有限以及数据删除无法验证的问题，在边缘计算环境下提出一种基于区块链的微电网数据安全存储与删除验证方案。利用边缘计算对电力数据进行预处理，减小数据规模，提高数据质量；分别基于K-Raft(Kademlia-Raft)和Streamlet共识协议构建安全存储链与删除验证链，前者存储密文哈希等相关信息，后者存储删除证明，实现真正的分布式存储。安全性分析与实验分析表明，该方案可以实现微电网数据的安全存储以及外包数据的高效删除验证。更多还原

【Abstract】 In view of the limited storage capacity of blockchain and the problem that data deletion cannot be verified, a secure storage and deletion verification scheme of microgrid data based on blockchain was proposed in the edge computing environment. The edge computing was used to preprocess the power data, reduce the data scale and improve the data quality. A secure storage chain and a deletion verification chain were constructed based on K-Raft(Kademlia-Raft) and Streamlet consensus protocol respectively. The ciphertext hash and other related information were stored in the former, while the deletion certificates were stored in the latter to realize distributed storage really. Security analysis and experimental analysis shows that the proposed scheme can realize not only the secure storage of microgrid data, but also the efficient deletion verification of outsourced data.更多还原
