Disaster Tolerance and Backup Scheme of Power Data Based on Blockchain
摘要
Due to the large volume,various types and high security requirements of power data,its disaster tolerance and backup scheme should provide scalability and privacy protection.Blockchain is tamper-resistant,decentralized and traceable,which caters to such requirements.Therefore,this paper proposes a new blockchain-based disaster recovery and backup scheme of power data,integrating AONT,threshold secret sharing and other cryptographic technologies.The prototype system is implemented on an open-source blockchain platform,Ethereum.Experimental and Analysis results show that the scheme can ensure the consistency,tamper resistance and confidentiality of backup data.It is highly scalable,reducing the construction cost of infrastructure as well as the risk of single point of failure.
