摘要: 对于种类众多、数量庞大并且安全性要求较高的电力数据,数据容灾备份应具有可扩展性和隐私保护性。为此,基于区块链不可篡改、去中心化和可追溯的特点,将其与AONT和门限秘密分享等密码学技术相结合,提出一种新的电力数据容灾备份方案,并在开源区块链平台以太坊上进行原型系统实现。分析与实验结果表明,该方案能够保证备份数据的一致性、不可篡改性和机密性,并且可扩展性强,可在减少基础设施建设开销的同时规避单点失效的风险。

Abstract: 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.

Key words: blockchain, power data, disaster tolerance and backup, data security protection, threshold secret sharing, All or Nothing Transform(AONT) technology
