Abstract

For power data with many types, large quantities and high security requirements, data disaster recovery backup should have scalability and privacy protection. To this end, based on the characteristics of blockchain immutable, decentralized and traceable, combining it with cryptography technologies such as AONT and threshold secret sharing, a new power data disaster backup scheme is proposed, and prototype system implementation is carried out on the open source blockchain platform Ethereum. The analysis and experimental results show that the scheme can guarantee the consistency, immutability and confidentiality of backup data, and has strong scalability, which can reduce the cost of infrastructure construction and avoid the risk of single point failure.
