Abstract
Port side channel attacks in multi-dimensional dynamic networks are concealed and random,and there are many attack sources and the attack paths are vague,which make it difficult to locate the attack sources quickly and accurately.Therefore,a fast location method for port side channel attacks in multi-dimensional dynamic networks is proposed.The frequency offset of the signals transmitted on the port side channel is used to obtain the distribution characteristics of the channel attacks,and the density-based spatial clustering of applications with noise(DBSCAN)is used to perform cluster analysis to detect the port side channel attacks.The region where the attack occurs is gridded.The iterative soft threshold algorithm and singular value decomposition(SVD)algorithm are combined to obtain the decomposition format of each node,and a fast channel attack location model is constructed,which is solved by a group sparse global least squares algorithm to quickly locate the channel attack.Simulation results show that the proposed method can obtain high-precision fast channel attack location results.The false alarm probability of the proposed method is only 0.02%,its detection time is only 1.56 ms,and its CPU utilization rate is no more than 10%,so the method can ensure stable operation of multi-dimensional dynamic networks.关键词
