Soeks-based intrusion detection method and implementation of vehicle electronic information system

Abstract

The invention belongs to the field of knowledge engineering and vehicle network communication and its security technology, and discloses a SOEKS-based vehicle electronic information system intrusion detection method and its realization. The vehicle CAN bus safety gateway is provided with a main control module including: a microprocessor and an external memory ; The external memory is used to store the experience set knowledge structure data experience set knowledge structure; the intrusion detection method includes: using the trained experience set knowledge structure to process and analyze the data on all buses, and continuously use the experience set knowledge structure in the process of processing and analysis Rules and constraints are used to judge whether the current information is correct and valid; if the change of a node value in the analysis results deviates from the normal range or the relationship between multiple nodes deviates far from the normal range, the car is detected to be intruded. If the present invention finds abnormal data, it will notify the driver in time, so as to prevent dangerous driving behavior of the car and ensure the personal and property safety of the driver.

Description

technical field [0001] The invention belongs to the technical field of knowledge engineering, vehicle network communication and information security thereof, and in particular relates to a SOEKS-based vehicle electronic information system intrusion detection method and its realization. Background technique [0002] At present, cars have become the daily means of transportation for most people. Under the same standard of performance, most car manufacturers have begun to pursue the entertainment of cars. Car functions are becoming more and more abundant, but at the same time it also brings some potential safety threats. . In recent years, there have been more and more reports of car attacks. In August 2015, DEFCON, the world's largest hacker conference, showed many car attack processes. In addition, the two hackers Charlie Miller and Chris Valasek in the JEEP car cracking incident chose to start with the JEEP entertainment system, and then control the car's brakes and other c...

Problems solved by technology

[0003] At present, the main way to ensure security is information encryption and intrusion detection technology, but due to the limited internal space of the automotive network and the timeliness requirements, it is difficult to use information encryption technology
