Security-Aware Approximate Spiking Neural Networks. (arXiv:2301.05264v1 [cs.CR])

Deep Neural Networks (DNNs) and Spiking Neural Networks (SNNs) are both known
for their susceptibility to adversarial attacks. Therefore, researchers in the
recent past have extensively studied the robustness and defense of DNNs and
SNNs under adversarial attacks. Compared to accurate SNNs (AccSNN), approximate
SNNs (AxSNNs) are known to be up to 4X more energy-efficient for ultra-low
power applications. Unfortunately, the robustness of AxSNNs under adversarial
attacks is yet unexplored. In this paper, we first extensively analyze the
robustness of …
