Research on Intrusion Detect System of Internet of Things based on Deep Learning

In this paper, by combining the known deep learning related literature in the field of intrusion detection, and the existing in the design of intrusion detection system based on the deep learning common low detection efficiency and high rate of false positives, as well as the training data set used by the problems of unbalanced data, etc., through the depth study of feature extraction and data processing ability. To study the intrusion detection method of the Internet of Things based on deep learning. The work and achievements are as follows:First of all, will be used for feature selection embedded model (EM) and used in intrusion detection of the convolution neural network (CNN), combined with lightweight intrusion detection model (XCNN), because it is an embedded model (EM), so can reduce the impact on the equipment, at the same time compared with other algorithms, the computing time is shorter, the same or even better.Second, proposed to the Attention mechanism (Self - Attention) is applied to intrusion detection system, due to the nature of the Attention mechanism, the mechanism and long Attention can greatly reduce the training time, through introducing the residual network, application feature coding technique again the sparse features thickened into low density at high altitudes, and join to its relative position encoding, So it can sense global information and solve the long-term dependence problem of recurrent neural network.Finally, the results of the intrusion detection method were analyzed on the Pthon simulation platform, and the relevant indicators were verified by using THE NSL-KDD dataset, THE CIC-IDS2017 dataset and the CSE-CIC-IDS2018 dataset. The effectiveness of the method was proved by building a laboratory Internet of Things environment for actual testing. The experimental results show that the algorithm can greatly reduce training time, improve training efficiency, and have the same or even better performance results.
