The Takeaway

With global supply chains, there is a constant fear that 'backdoors' or kill-switches could be built into hardware at the factory. This tool uses image-recognition AI to verify every single microscopic metal line in a chip against its original blueprint, ensuring nothing extra was added during production.

From the abstract

In light of globalized hardware supply chains, the assurance of hardware components has gained significant interest, particularly in cryptographic applications and high-stakes scenarios. Identifying metal lines on scanning electron microscope (SEM) images of integrated circuits (ICs) is one essential step in verifying the absence of malicious circuitry in chips manufactured in untrusted environments. Due to varying manufacturing processes and technologies, such verification usually requires tuni
