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.
