Existing works indicate that Spiking Neural Networks (SNNs) are resilient to adversarial attacks by testing against few attack models. This paper studies adversarial attacks on SNNs using additional attack models and shows that SNNs are not inherently robust against many few-pixel L0 black-box attacks. Additionally, a method to defend against such attacks in SNNs is presented. The SNNs and the effects of adversarial attacks are tested on both software simulators as well as on SpiNNaker neuromorphic hardware.

Based on the third generation neural network spiking neural network, this paper optimizes and improves a classification and coding method, and proposes an image recognition method. Firstly, the read image is converted into a spike sequence, and then the spike sequence is encoded in groups and sent to the neurons in the spike neural network. After learning and training for many times, the quantization standard code is obtained. In this process, the spike sequence transformation matrix and dynamic weight matrix are obtained, and the unclassified data are output through the same matrix for image recognition and classification. Simulation results show that the above methods can get correct coding and preliminary recognition classification, and the spiking neural network can be applied.
