Title: ON-BOARD VEHICLE NETWORK SYSTEM AND METHOD FOR DETECTING INTRUSIONS ON THE ON-BOARD NETWORK
Abstract:
The invention relates to a method of real-time detection of intrusions in an on-board vehicle communication network, comprising the steps of observing (100) a stream of messages transmitted over the on-board network and detecting intrusions when the observed stream contains a prohibited message. The invention is characterized in that the method comprises at least one step of: - accessing (103, 107), in the memory of at least one on-board computer of the vehicle, at least one data structure encoding prohibited message sequences transmitted over the on-board network, - detecting (104, 108) an intrusion when observation of the stream reveals a prohibited message to be a final message in a prohibited sequence.
