摘要:

高级量测体系(AMI)是新型电力系统的关键组成部分,异构通信网络和智能终端的广泛应用导致其易受到网络攻击威胁.本文研究分布式拒绝服务(DDoS)攻击下AMI网络的动态建模与最优防御策略.首先,分析DDoS攻击在AMI网络中的传播路径,并结合复杂网络理论与SEIR传染病模型,建立一个刻画AMI网络中节点遭受DDoS攻击后的状态演化模型,分析DDoS攻击在AMI网络中的传播机理和攻击容忍水平.然后,以最小化防御损失和成本为目标提出一种在AMI网络中灵活优化部署防御资源的防御策略.最后,在两种不同的AMI网络结构下进行大量数值仿真,验证了所提策略的有效性.

Abstract:

Advanced metering infrastructure (AMI) is a key component of new power systems. However, the wide application of heterogeneous communication networks and intelligent terminals makes it vulnerable to cyber-attacks. Therefore, this paper studies the dynamic modeling and optimal defending strategy of AMI network under distributed denial-of-service (DDoS) attacks. First, the propagation path of DDoS attack in AMI network is analyzed. Combined with the complex network theory and the SEIR epidemic model, a state evolution model is established to describe the state evolution of nodes after DDoS attack and the propagation mechanism and attack tolerance level of DDoS attack in AMI network are analyzed. Then, a defending strategy is proposed with the goal of minimizing defense losses and costs to flexibly optimize the deployment of defense resources. Finally, the effectiveness of the proposed strategy is verified by using a large number of numerical simulations in two different AMI network structures.

Key words: advanced metering infrastructure (AMI), distributed denial-of-service (DDoS) attacks, dynamic SEIR epidemic model, complex network theory, optimal control
