本文介绍了一种基于热传感器的有效检测恶意硬件的技术。每个传感器由一个带有三个反相器的环形振荡器、一个控制多路复用器和一个仅需要两个 FPGA 片的紧凑型残留数系统环形计数器组成。传感器以彼此等距离放置在 6x5 网格结构中，以覆盖 FPGA 实现的整个区域，从而导致总开销仅为 1.9%。为了模拟硬件木马，使用了 64 位线性反馈移位寄存器。我们通过基于 XILINX Basys 3 板的实验系统演示了所提出的技术。实验结果说明了所提出技术的效率。据我们所知，我们是第一个使用这种传感器进行硬件木马检测的公司。
This paper introduces an efficient technique for the detection of malicious hardware, based on thermal sensors. Each sensor consists of a Ring Oscillator with three inverters, a control multiplexer and a compact Residue Number System ring counter requiring only two FPGA slices. The sensors were placed in a 6x5 grid structure in equal distance from each other, in order to cover the whole area of the FPGA implementation causing a total overhead of only 1.9 %. To emulate a Hardware Trojan, a 64-bit Linear Feedback Shift Register was used. We demonstrate the proposed technique with an experimental system based on a XILINX Basys 3 board. The results from the experiments illustrate the efficiency of the proposed technique. According to our knowledge we are the first that we have used this kind of sensor for Hardware Trojan Detection.
