摘　　要：随着电力网与信息网的进一步融合,传统电网逐渐向电力信息物理系统靠近。由于节点遭受恶意攻击时,很容易发生篡改数据或者数据丢失等数据安全问题。为了更好地存储电力信息物理系统中的数据,提出利用区块链技术设计一个数据安全存储方案。利用改进之后的实用拜占庭容错算法实现节点之间的共识,对新区块的生成进行广播,达到防御恶意攻击的目的。在仿真实验中分析了不同规模的共识节点处理客户端提交请求的通信时间和通信开销。分析表明,所提方案可以解决电力信息物理系统的数据安全问题,抵御恶意攻击,并且相比其他方案具有优越性。With the further integration of power network and information network,the traditional power grid is gradually ap⁃proaching the Cyber Physical Power Systems.When a node is subjected to malicious attacks,data security issues such as data tam⁃pering or data loss are likely to occur.In order to better store the data in the Cyber Physical Power Systems,it is proposed to use blockchain technology to design a data security storage scheme,the improved practical Byzantine fault-tolerant algorithm is used to achieve consensus between nodes,and the generation of new blocks is broadcast to achieve the purpose of preventing malicious at⁃tacks.In the simulation experiment,the communication time and communication overhead of consensus nodes of different sizes to process client submission requests are analyzed.The analysis shows that the proposed scheme can solve the data security problem of the Cyber Physical Power Systems,resist malicious attacks,and have advantages over other schemes.
