我们重新讨论对抗性丢包链路上的一步控制问题。该链路被建模为一组由战略干扰器控制的二进制信道，其目的是通过选择最具破坏性的信道切换策略对工厂发动“拒绝服务”攻击。本文引入了一类干扰者与控制者之间的零和博弈作为这种攻击的一个场景，并推导了该类博弈具有非平凡鞍点平衡的充分必要条件。在此平衡状态下，干扰器的最优策略是随机化设备状态空间的一个区域，因此要求控制器进行非平凡响应，这与在丢包信道上的标准随机控制问题中所期望的响应不同。
We revisit a one-step control problem over an adversarial packet-dropping link. The link is modeled as a set of binary channels controlled by a strategic jammer whose intention is to wage a `denial of service' attack on the plant by choosing a most damaging channel-switching strategy. The paper introduces a class of zero-sum games between the jammer and controller as a scenario for such attack, and derives necessary and sufficient conditions for these games to have a nontrivial saddle-point equilibrium. At this equilibrium, the jammer's optimal policy is to randomize in a region of the plant's state space, thus requiring the controller to undertake a nontrivial response which is different from what one would expect in a standard stochastic control problem over a packet dropping channel.
