Method for vehicle intrusion detection with mobile router
First Claim
1. A method of operating a mobile router installed in a vehicle, said vehicle comprising a vehicle network bus coupled to a plurality of electronic control units each of said electronic control units comprising a separate processor and a separate physical memory, said mobile router comprising:
- a wireless wide area network interface to access a wireless wide area network, a wireless local area network interface operable to provide a wireless local area network mobile with said mobile router, an interface to said vehicle network bus coupled to said plurality of electronic control units, a separate processor, a separate physical mobile router memory, and an intrusion detection program stored in said separate physical mobile router memory and executable by said mobile router separate processor to detect electronic intrusions, said mobile router operable to route data between one or more mobile devices located in said vehicle coupled to said wireless local area network mobile with said router and said wireless wide area network, said method comprising;
isolating said intrusion detection program to insure the integrity of said intrusion detection program;
utilizing one or more memory isolation approaches to isolate said intrusion detection program stored in said separate physical mobile router memory from any other program or programs to insure said integrity of said intrusion detection program;
monitoring data on said vehicle network bus;
utilizing said intrusion detection program to detect one or more anomalies in said monitored data indicative of an electronic intrusion; and
generating an alert indicative of an electronic intrusion upon detection of said one or more of anomalies indicative of an electronic intrusionsaid one or more anomalies indicative of an electronic intrusion comprise re-flashing of an electronic control unit memory and predetermined radio frequency hub activity in said vehicle of a type that comprise attempts to determine a predetermined code assigned to said vehicle; and
receiving at least one of calibration information and update information for said intrusion detection program via a selected one of said wireless wide area network interface and said wireless local area network interface.
