On-Chip Laser Voltage Probing Attack Detection with 100% Area Coverage at Above/Below the Bandgap Wavelength and Fully-Automated Design

An on-chip detection scheme against Laser Voltage Probing (LVP) attacks is introduced. It enables digital IP full-area coverage, and its architecture preserves automated design and stdcell layout discipline (including restricted design rules). Stdcells with laser sensing are proposed with photocurrent sensitivity up to 4~10 pA/ μm
