Title : Machine Learning based Attack Method against Artificial Noise-aided Secure Communication
 
Abstract:
 
Physical layer security (PLS) technologies have attracted much attention in recent years for its potential of providing information-theoretical secure communication. Artificial Noise-aided (AN) transmission is considered as one of the most practicable PLS technologies, as its secure transmission doesn’t involve the channel information of the eavesdropper. However, the performance of AN transmission under the condition of that the eavesdropper has more antenna than the transmitter, hasn’t been investigated sufficiently and may be one of the serious obstacles of AN’s realization. In this talk, an effective attack method based on machine learning approach, to attack AN transmission and evaluate its performance will be presented. In our method, we assume that the received signals in the eavesdropper are distributed in different hyper-planes corresponding to the constellation points of modulation, therefore adopt a clustering algorithm to estimate the channel between transmitter and receiver to decode the AN-aided packet. Numerous simulation results show that our algorithm performs much better than the conventional method and can decode AN-aided transmission with varies modulation method. We also evaluated in which condition can AN transmission achieve secure communication, even when eavesdropper equipped with our effective attack method.
