Vehicle electronic information system intrusion detection method based on SOEKS and implementation

Abstract

The invention discloses a vehicle electronic information system intrusion detection method based on SOEKS and the implementation, belonging to the technical fields of knowledge engineering, vehicle network communication and security. A main control module is arranged on the security gateway of the vehicle CAN bus, and the main control module comprises a microprocessor and an external memory; and the external memory is used to store the experience set knowledge structure data. The vehicle electronic information system intrusion detection method comprises the following steps: processing and analyzing the data on all buses by means of the trained experience set knowledge structure, and using the rules and constraints in the experience set constantly in the process of processing and analysis to determine whether the current information is correct and effective; and detecting the intrusion if the change of a node value in the analysis results deviates from the normal range or the incidencerelationship between multiple nodes is far away from the normal range. According to the invention, if abnormal data is found, the driver will be notified in time to prevent the dangerous driving of the vehicle, therefore, the safety of the person and the property of the driver can be ensured.

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...
