瞬态效应环形振荡器（TERO）是环形振荡器（RO）设计的一种特殊情况，它对固有噪声的灵敏度增加。它可以作为实现真随机数生成器（TRNG）或物理不可克隆功能（PUF）的基础。此外，作为用于检测数字电路中的恶意硬件逻辑（木马）的插入的数字传感器。在这里，我们探讨TERO检测硬件木马注入的AES加密算法的FPGA实现中的应用。实验和比较报告的频率作为TERO长度的函数。我们的研究结果表明，基于TERO的数字传感器可以用来有效地检测木马的存在。
A Transient Effect Ring Oscillator (TERO) is a special case of a Ring Oscillator (RO) design that exhibits increased sensitivity to intrinsic noise. It can serve as a basis for implementing a True Random Number Generator (TRNG) or a Physically Uncloneable Function (PUF). Also, as a digital sensor for detecting insertion of malicious hardware logic (Trojans) in digital circuits. Here, we explore the application of TERO for detecting hardware Trojans injected in FPGA implementations of the AES cryptographic algorithm. Experiments and comparisons are reported in terms of the frequency as a function of the TERO length. Our findings indicate that TERO-based digital sensors can be used to efficiently detect the presence of the Trojan.
