Intel NCS2 Fault Response Under Electromagnetic Injection
A comprehensive single-pulse electromagnetic fault injection (EMFI) study on the Intel Neural Compute Stick 2 (NCS2) identified four distinct outcome categories. Researchers executed 1,536 spot-test trials at specific hotspots and around 16,000 parameter-search trials while utilizing three convolutional neural networks trained on ImageNet (ResNet-18, ResNet-50, VGG-11) within the OpenVINO runtime. The results from single pulses indicated no change in accuracy, minor silent data corruption, significant persistent degradation that lasted through subsequent inferences until the model was reloaded, and device hangs. This research highlights the inadequately understood fault responses of vision processing units in critical edge applications.
