|---|---|---|
With the separation of design and manufacture in semiconductor industry, self-designed circuits are exposed to hardware Trojan attacks when they are outsourced to an untrustworthy foundry. Trojans activated by digital logic have gained extensive attention. However, those with analog trigger component remain as a serious issue such as the A2 Trojan. Existing defense against A2 Trojans mainly relies on runtime detection mechanism which needs large monitor hardware overhead and complicated identification/handling software. To address these limitations, this article proposes a built-in structure to accelerate the activation of A2 Trojans, which consists of several composite-logic ring oscillators and a multiple-purpose controller. In addition, two post-fabrication detection schemes named time-division mode-switching (TDMS) and scan-based fault test compatible (SFTC) are proposed. TDMS detection scheme can discover A2 Trojans when running functional patterns by inserting oscillating operations every other cycle. SFTC detection scheme can detect A2 Trojans during scan-based fault test by introducing oscillation before each capture operation. Evaluations across a wide range of A2 Trojans and benchmarks show that our proposal is more power-efficient and area-saving compared with existing monitor structure. |
