摘要
本文针对制冷空调领域数据加密共享问题,提出了一种基于区块链的大数据加密与共享方案。使用类型与身份的代理重加密技术实现对数据的加密,构建私有链用于存储各个空调厂商的加密的数据,联盟链用于存储各厂商数据的索引记录和加密数据并作为数据共享中介。对所提方案的安全性和可用性进行分析与评估表明,该方案能有效地实现对空调厂商大数据的加密与共享。
Aiming at the problem of data encryption and sharing in the field of refrigeration and air conditioning,a blockchain-based big data encryption and sharing scheme is proposed in this paper. The proxy re-encryption technology of type and identity is used to encrypt data, and a private chain is constructed to store the encrypted data of each air conditioner manufacturer. The alliance chain is used to store the index records and encrypted data of each manufacturer’s data and act as a data sharing intermediary. The analysis and evaluation of the security and usability of the proposed scheme show that the scheme can effectively realize the encryption and sharing of big data of air conditioner manufacturers.
