Integrated Circuits (ICs) are becoming increasingly vulnerable to malicious alterations, referred to as hardware Trojans. Detection of these inclusions is of utmost importance, as they may potentially be inserted into ICs bound for military, financial, or other critical applications. A novel on-chip structure including a Ring Oscillator Network (RON), distributed across the entire chip, is proposed to verify whether the chip is Trojan-free. This structure effectively eliminates the issue of measurement noise, localizes the measurement of dynamic power, and additionally compensates for the impact of process variations. Combined with statistical data analysis, the separation of process variations from the Trojan contribution to the circuit's transient power is made possible.
