摘要
无线通信网络的脆弱性使得工业信息物理系统易遭受各类网络攻击.为了更深入地了解不同网络攻击的特征进而建立有效的防御措施,构建一种线性时不变离散系统的工业信息物理系统结构;深入研究信息物理系统攻击者攻击空间及攻击者攻击模型,采用控制理论方法研究攻击空间模型的模型知识、披露资源和破坏资源的数学表达;对拒绝服务攻击、重放攻击、虚假数据注入攻击3种典型网络攻击的基本特性,以及对应攻击下攻击模型的表现形式进行分析.通过Simulink/Truetime仿真工具对破坏性和隐蔽性性能进行仿真实验.结果表明,所研究的攻击空间模型及攻击者攻击模型能够有效地描述网络攻击的攻击特性.
The fragility of wireless communication networks makes industrial cyber physical systems vulnerable to suffer various types of network attacks.In order to research the characteristics of different network attacks for establishing effective defense measures,this paper constructs an industrial cyber physical systems structure based on linear time-invariant discrete systems.The attack space and the attacker attack model of the cyber physics system are deeply studied.The control theory method is used to establish the mathematical expression of the model knowledge,disclosure resource and the broken resource.The basic characteristics of three typical network attacks,such as denial of service attack,replay attack and false data injection attack,and the manifestations of attack models under corresponding attacks are analyzed.Simulation experiments are conducted to evaluate the performance of destructiveness and concealment by using the Simulink/Truetime simulation tool.The simulation results show that the attack space model and the attacker attack model can effectively describe the attack characteristics of network attacks.
