赛博物理系统（CPS）是由数字（赛博）计算和物理运动之间独特的相互作用定义的。它们的混合性质引入了新的攻击媒介，但也为设计新的安全防御提供了机会。在本文中，我们提出了一种新的特定于域的安全机制，YOLO，利用物理属性，如惯性，以提高安全性。YOLO很容易描述。它经历两个操作：重置和多样化，尽可能频繁-通常在几秒钟的顺序。重置减轻了旨在实现持久性和增强多样化技术的攻击。由于惯性，CPS即使在频繁重置的情况下也可以保持安全。我们引入了一种分析方法来评估YOLO化系统的可行性。使用这个分析模型，我们定义了重置周期的约束，以保持CPS的稳定性。我们评估我们的方法在模拟和两个真实的系统：发动机控制单元（ECU）的汽车和飞行控制器（FC）的四轴飞行器。从我们的实验中，我们确定重置可以频繁触发，ECU的每125 ms和FC的每秒都一样快，而不会违反安全性。
A Cyber-Physical System (CPS) is defined by its unique interactions between digital (cyber) computation and physical motion. Their hybrid nature introduces new attack vectors, but also provides an opportunity to design new security defenses. In this paper, we present a new domain-specific security mechanism, YOLO, that leverages physical properties such as inertia to improve security. YOLO is simple to describe. It goes through two operations: Reset and Diversify, as frequently as possible – typically in the order of a few seconds. Resets mitigate attacks that aim to achieve persistence and enhance the power of diversification techniques. Due to inertia, CPSs can remain safe even under frequent resets. We introduce an analytical approach to evaluate the feasibility of a YOLO-ized system. Using this analytical model we define the constraints on reset periods in order to maintain the CPS’s stability. We evaluate our approach in simulation and on two real systems: an engine control unit (ECU) of a car and a flight controller (FC) of a quadcopter. From our experiments, we determine that resets can be triggered frequently, as fast as every 125ms for the ECU and every second for the FC, without violating safety.
