Abstract:

To address issues in data disaster recovery backup solutions such as low data security, susceptibility to data loss and damage, and excessive reliance on third-party services, a blockchain-based data disaster recovery backup scheme for cloud-edge collaborative grid status monitoring was proposed. Firstly, a cloud-edge collaboration approach was adopted to enhance the efficiency of monitoring data backup. Secondly, the Paillier algorithm and threshold secret sharing were combined to encrypt monitoring data, achieving distributed backup. Finally, an improved Hot-Stuff consensus mechanism was applied to blockchain to optimize its consensus efficiency. Security analysis results demonstrate that the proposed scheme ensures privacy, integrity, unforgeability, and correctness; performance analysis results show that the scheme reduces backup and recovery latency, shortens backup and recovery time, lowers computational overhead, and increases throughput.

Key words: blockchain, disaster recovery backup, status monitoring, cloud collaboration, consensus mechanism

摘要:

针对数据容灾备份方案存在的数据安全性低、易丢失和损坏、过度依赖第三方服务等问题,提出一种云边缘协同电网状态监测数据区块链灾备方案。首先采用云边缘协同方式提高监测数据备份效率;其次结合Paillier算法和阈值秘密共享对监测数据进行加密保护,实现分布式备份;最后将改进的Hot-Stuff共识机制应用于区块链,提高区块链的共识效率。安全性分析结果表明,该方案具有隐私性、完整性、不可伪造性和正确性;性能分析结果表明,该方案缩短了备份与恢复延迟以及备份与恢复耗时,降低了计算开销,且提高了吞吐量。
