摘要:

自动驾驶汽车等自动驾驶系统依靠传感器来感知周围的世界。必须采取措施防止对传感器的攻击,这在过去几年中一直是一个热门话题。为了实现这一目标,必须首先评估传感器攻击如何影响系统,即如果某些内置传感器受损,系统的哪个部分或整个系统将失败,或者将保持安全等。另一方面,ISO/SAE 21434解决了车辆系统开发过程中的安全问题,但没有解决传感器攻击等特定威胁。因此,传感器攻击下的自主系统的安全性还有待解决。在本文中,我们提出了一个框架,结合安全分析的情况下识别,和基于MIMO的模拟传感器攻击模型嵌入式。给定一个自治系统模型,我们确定危险的情况下所造成的传感器攻击,并评估的情况下的性能限制。我们报告了一个带有雷达、摄像头和激光雷达的自动驾驶汽车原型模拟器,以及针对传感器的攻击模型。我们的实验表明,我们的框架可以评估系统的安全性如何变化的参数的攻击和传感器的变化。

英文摘要:

Autonomous systems such as self-driving cars rely on sensors to perceive the surrounding world. Measures must be taken against attacks on sensors, which have been a hot topic in the last few years. For that goal one must first evaluate how sensor attacks affect the system, i.e. which part or whole of the system will fail if some of the built-in sensors are compromised, or will keep safe, etc. Among the relevant safety standards, ISO/PAS 21448 addresses the safety of road vehicles taking into account the performance limitations of sensors, but leaves security aspects out of scope. On the other hand, ISO/SAE 21434 addresses the security perspective during the development process of vehicular systems, but not specific threats such as sensor attacks. As a result the safety of autonomous systems under sensor attack is yet to be addressed. In this paper we propose a framework that combines safety analysis for scenario identification, and scenario-based simulation with sensor attack models embedded. Given an autonomous system model, we identify hazard scenarios caused by sensor attacks, and evaluate the performance limitations in the scenarios. We report on a prototype simulator for autonomous vehicles with radar, cameras and LiDAR along with attack models against the sensors. Our experiments show that our framework can evaluate how the system safety changes as parameters of the attacks and the sensors vary.
