Self-Referenced Design-Agnostic Laser Voltage Probing Attack Detection with 100% Protection Coverage, 58% Area Overhead for Automated Design

Abstract

A self-referenced distributed on-chip scheme is introduced to achieve continuous detection of laser voltage probing (LVP) attacks against digital IPs with full-area coverage via temperature sensing. Calibration-free, automated and design-agnostic adoption are enabled by a stdcell-based approach, offering a 2.5X area overhead reduction compared to prior art.
