The invention discloses a CAN intrusion detection system of an automobile gateway. The CAN intrusion detection system comprises a synchronous labeling module, an RB detection module, a DLB detection module and a detection convergence module, the processing flow of the CAN intrusion detection system comprises the following steps: after receiving a CAN data frame, sending the CAN data frame to a synchronous labeling module for synchronous labeling; after the synchronous labeling module completes processing, sending the data frame to the RB detection module and the DLB detection module at the same time for parallel detection processing, and sending detection results of the RB detection module and the DLB detection module to the detection convergence module for processing, wherein the detection convergence module gives a final detection result to confirm whether an attack or a normal response exists or not. Double-module detection of the DLB detection module based on deep learning and the RB detection module based on rules is adopted according to automobile network conditions, low calculation requirements are kept through RB detection, high predictability results are achieved through DLB detection, intrusion behaviors can be effectively and quickly responded, and further attack and damage are prevented.
Description
technical field [0001] The invention relates to the field of automobile network security, in particular to a real-time CAN intrusion detection system of an automobile gateway. Background technique [0002] With the Internet of cars, remote intrusion attacks on cars are constantly being reported, and car network security has become a problem that every car manufacturer must consider. For this potential intrusion risk, there are many traditional intrusion detection methods, but they are not suitable for use in the automotive network environment. This ensures that it is used in real time in the automotive environment to respond to intrusion situations in real time. Therefore, it is necessary to design a system that can quickly detect CAN intrusion behavior on the automotive gateway in real time, so as to respond quickly to the intrusion behavior and prevent further attack damage. Contents of the invention [0003] In view of the above-mentioned defects of the prior art, the...
