摘要:

我们研究了在存在拒绝服务(DoS)攻击下的通信受限网络控制问题,即攻击阻止通信网络传输的攻击。我们的工作旨在探讨系统鲁棒性与网络带宽容量之间的关系。给定一类DoS攻击,我们首先确定了时间不变的比特率上限,该上限依赖于动态矩阵的不稳定特征值和DoS攻击参数,超过该上限可保证闭环系统指数稳定性。其次,我们设计了时间变化的比特率协议,证明该协议可使系统保持与时间不变比特率协议相当的鲁棒性,同时在攻击级别较低时促进更少的比特传输。我们的分析清楚地展示了通信带宽与对抗DoS攻击的鲁棒性之间的权衡。通过一个例子来说明所提出的方法。

英文摘要:

We study communication-constrained networked control problems for linear time-invariant systems in the presence of Denial-of-Service (DoS) attacks, namely attacks that prevent transmissions over the communication network. Our work aims at exploring the relationship between system resilience and network bandwidth capacity. Given a class of DoS attacks, we first characterize time-invariant bit-rate bounds that are dependent on the unstable eigenvalues of the dynamic matrix of the plant and the parameters of DoS attacks, beyond which exponential stability of the closed-loop system can be guaranteed. Second, we design the time-varying bit-rate protocol and show that it can enable the system to maintain the comparable robustness as the one under the time-invariant bit-rate protocol and meanwhile promote the possibility of transmitting fewer bits especially when the attack levels are low. Our characterization clearly shows the trade-off between the communication bandwidth and resilience against DoS. An example is given to illustrate the proposed solution approach.
