Practical Software Countermeasures 4 Hardware Glitch Attacks- Arshid & Chinmay
Nullcon Goa 2025 · Main Stage
In an era where software vulnerabilities often dominate security discussions, the realm of **hardware security** presents a distinct and increasingly critical challenge. This talk, "Practical Software Countermeasures 4 Hardware Glitch Attacks," delivered by Arshid and Chinmay, delves into the often-overlooked threat posed by physical attacks on embedded systems. Specifically, it focuses on **fault injection attacks**, where an attacker manipulates the physical environment of a device—such as its power supply or clock signal—to induce transient errors in its operation, thereby bypassing security mechanisms like password checks or secure boot.
AI review
Competent, well-structured introduction to software fault injection countermeasures with real measurements and a live demo. The volatile/duplication/inversion/masking taxonomy is clearly explained and the 'negation of logic' gotcha is genuinely instructive. Nothing here is new to anyone who's read the ChipWhisperer docs or Riscure's training material, but it's executed honestly and without vendor hype.
