Networked automobile communication data abnormal transmission behavior detection method and system

Abstract

The invention provides a networked automobile communication data abnormal transmission behavior detection method and system. The method comprises the following steps: acquiring uplink and downlink communication data to be detected between a vehicle and a cloud platform in real time; comparing the uplink and downlink communication data to be detected with normal transmission models corresponding to vehicle brands and vehicle types based on a qualified platform list library, and judging whether the uplink and downlink communication data to be detected have abnormal transmission behaviors or not, wherein the qualified platform list library is established by processing the communication data by taking a cloud platform address in the communication data between the vehicle and the cloud platform as a feature, and the normal transmission model is established by processing communication data based on a cloud platform address in a qualified platform list library by taking a vehicle IMSI number as a characteristic. The method is used for overcoming the defect that a data detection method in the prior art cannot be applied to intelligent networked automobile data transmission detection, vehicle transmission data is detected through a qualified platform list library and a normal transmission model, and real-time detection of networked automobile communication data transmission behaviors is achieved.

Description

technical field [0001] The invention relates to the technical field of communication data transmission detection, in particular to a method and system for detecting abnormal transmission behavior of networked vehicle communication data. Background technique [0002] The intelligent networked car realizes the deep coupling between the traditional closed car world and the Internet space, so that all kinds of information of vehicles, roads, people, and clouds can be connected to the Internet space through the Internet of Vehicles, and the remote control, remote diagnosis, and Function upgrade has become an important trend in the future. With the extensive application of intelligence, networking, and digitalization in the traditional automobile industry, in order to develop automatic driving functions and smart cockpit experience, intelligent networked vehicles widely collect video information of the surrounding environment, personal information, vehicle status information, etc....

AI Technical Summary

Problems solved by technology

[0012] The invention provides a method and system for detecting abnormal transmission behavior of networked vehicle communication data, which is used to solve the defect that the data detection method in the prior art cannot be applied to the detection of intelligent networked vehicle data transmission. Based on the normal transmission model of the vehicle brand and model, the vehicle transmission data is detected, and the real-time detection of the networked vehicle communication data transmission behavior is realized.
