摘要

我们提出了一种新型传感器，它扩展了传统物理不可克隆功能的功能，以提供对感测值的身份验证、不可克隆性和验证。这种新型设备解决了典型传感系统中的漏洞，攻击者可以通过干扰从传感器元件传递到嵌入式微处理器的模拟信号来欺骗测量。该概念可应用于任何类型的模拟传感器。

Sensor physical unclonable functions

We propose a novel variety of sensor that extends the functionality of conventional physical unclonable functions to provide authentication, unclonability, and verification of a sensed value. This new class of device addresses the vulnerability in typical sensing systems whereby an attacker can spoof measurements by interfering with the analog signals that pass from the sensor element to the embedded microprocessor. The concept can be applied to any type of analog sensor.
