Abstract

This paper presents a study about hardware attacking and clock signal vulnerability. It considers a particular type of attack on the clock signal in the I2C protocol, and proposes the design of a new sensor for detecting and defending against this type of perturbation. The analysis of the attack and the defense is validated by means of a configurable experimental platform that emulates a differential drive robot. A set of experimental results confirm the interest of the studied vulnerabilities and the efficiency of the proposed sensor in defending against this type of situation.

摘要

本文介绍了一项关于硬件攻击和时钟信号漏洞的研究。它考虑了对I2C协议中时钟信号的一种特定类型攻击，并提出了一种用于检测和抵御此类干扰的新型传感器的设计。通过一个模拟差分驱动机器人的可配置实验平台对攻击和防御进行了分析验证。一组实验结果证实了所研究漏洞的重要性以及所提出传感器在抵御此类情况方面的有效性。
