Rolling code learning detection method and device, equipment and computer readable storage medium

Abstract

The invention provides a rolling code learning detection method and device, equipment and a computer readable storage medium; the method comprises the following steps: gathering message data; determining whether the message data rolling code rolling mechanism has been learned or not; if not, learning the rolling code rolling mechanism; detecting whether the rolling code is abnormal or not according to the rolling code rolling mechanism; if yes, forming abnormal information and uploading the same. The method can automatically learn the rolling code rolling mechanism from the gathered message data, thus detecting the rolling code in the message data in real time, realizing abnormity alarming, timely responding to abnormal data, and preventing packet loss risks in detection after the messagedata is uploaded.

Description

technical field [0001] The present application relates to the technical field of communication security, in particular to a rolling code learning and detection method, device, equipment, and computer-readable storage medium. Background technique [0002] Controller area network (Controller Area Network, referred to as CAN), developed by the German BOSCH company, and eventually became an international standard (ISO11898), CAN bus technology has been widely used in various detection and control systems. The CAN bus can be a peer-to-peer structure, that is, a multi-host working mode. Any node on the network can actively send information to other nodes on the network at any time. With the rapid development of intelligence in various fields in recent years, more and more sensors , The electronic control unit is added, the CAN bus data communication is more vulnerable to attack, and the communication reliability cannot meet expectations. For this reason, many manufacturers have a...

Problems solved by technology

[0003] The traditional data collection method and device using the rolling code mechanism does not have a real-time processing mechanism for the rolling code. The collected message data can only be stored locally, or uploaded and stored remotely, and then manually processed.

The disadvantage of the above scheme is that it is impossible to process the rolling code of the message data in real time, and when the data is abnormal (the corresponding rolling code is abnormal), it cannot be known in time to make a response. In addition, the scheme of post-processing the message data still exists The risk of abnormal packet loss
