Abstract :
Hardware Trojan horses are a realistic threat for both ASIC and FPGA systems. Ring Oscillators (ROs) can be used to detect the presence of malicious hardware functionality. The length of an RO is a significant parameter for detecting efficiently malicious logic (sensitivity) while maintaining a low space and power profile. We explore through simulation the effect of the RO length on detecting different classes of Trojan horses on an FPGA.
