Abstract

A security monitoring apparatus and method for a vehicle network are provided. The apparatus transmits an indicator and an encryption key to a plurality of electronic control units via the controller area network interface. The apparatus receives a response code from each electronic control unit via the controller area network interface, wherein each of the response codes is generated by a serial number of each electronic control unit and the encryption key via a hash algorithm. The apparatus compares the response code returned by each electronic control unit according to a list, the encryption key and the hash algorithm to determine whether each electronic control unit correctly returns the response code. The apparatus determines to generate an alert signal when one of the electronic control units does not correctly return the response code.

Description

technical field [0001] The invention relates to a safety monitoring device and method for a vehicle network. Specifically, the present invention relates to a safety monitoring device and method installed in a controller area network of a vehicle. Background technique [0002] With the rapid development of technology, various vehicles are equipped with various electronic control units (Electronic Control Unit; ECU) to control and detect various electronic devices installed on the vehicle and the combined components. Generally speaking, the vehicle network is also called the Controller Area Network (CAN). The Controller Area Network is a vehicle bus standard widely used in vehicles at present, allowing these electronic control units on the vehicle to pass through the controller area network. network bus to communicate with each other. [0003] However, since the internal communication of the controller area network is based on the broadcast mechanism of the information-orien...
