Problems solved by technology
However, the main problems of the hardware Trojan detection method based on bypass analysis include: (1) The verification experiment generally adopts the simulation method, mainly using the HSPICE environment and the ISCAS standard library for simulation
However, in the actual experiment, the bypass signal is seriously disturbed by noise, which is quite different from the simulation environment, making it difficult to reproduce the simulation conclusion in the actual experiment

Description
technical field [0001] The invention relates to the technical field of integrated circuit chip detection, in particular to a hardware Trojan horse detection system and a detection method thereof. Background technique [0002] With the further globalization of semiconductor design, manufacturing and use, especially the increasing popularity of hardware manufacturing outsourcing, integrated circuit (IC) chips are vulnerable to various types of malicious attacks, especially "Hardware Trojan" ". The so-called hardware Trojan horse is a malicious circuit formed by changing the original design of an IC to achieve the goals of function tampering, specification tampering, and information leakage. It can easily break through the existing security protection system and pose a huge threat. Hardware Trojan horses have the characteristics of exquisite design and strong concealment. Traditional chip testing methods such as physical inspection and functional testing are not up to the task...
