Single-Bit Fault Injection in Hardware Explored

⚡️ Exploring the Feasibility of Single-Bit Fault Injection in Hardware. Recent experiments in hardware fault injection reveal that while achieving single-bit flips is challenging, it is indeed possible under specific conditions. Utilizing voltage glitching techniques, researchers found that operating at 80MHz and 160MHz allowed for successful single-bit modifications, with varying success rates depending on the bit’s position. Notably, certain bits were more susceptible to changes than others, and the lowest operational voltage was not always the most effective. The study emphasizes the complexity of glitching and the influence of hardware configurations, suggesting that further exploration is needed to fully understand the mechanisms at play in fault injection attacks.
