The increasing use of embedded systems highlights the significance of hardware security, leading to research on hardware attacks. Fault injection attacks via voltage glitch represent a methodology with diverse applications. In this context, fault injection attacks were studied against a microcontroller executing the cryptographic algorithm AES-128, aiming to compute the cryptographic key using Differential Fault Analysis. The bit-level and byte-level fault models were examined and implemented at the simulation level using MATLAB. Subsequently, fault injection was implemented using Chipwhisperer nano attacking a single byte during the 8th round of AES. The results demonstrated high success rates in recovering the cryptographic key.
