Embodiment Construction

[0040] figure 1 is a block diagram of an exemplary vehicle bus anti-spoofing system 100. The sensor 111 is connected to an electronic control unit (ECU) 102, for example in a known manner. The ECU 102 has a controller 104 in communication with a communications controller 106 . Communication controller 106 is connected to anti-spoofing module 108 . Anti-spoofing module 108 is communicatively coupled to communication transceiver 110 . The communication transceiver 110 is correspondingly connected in communication with the bus 101 of the motor vehicle network. The bus 101 has impedance termination resistors 103 at each end of the bus 101 .

[0041] Controller 104 may include one or more processors, such as microprocessors or microcontrollers. Controller 104 may also have memory, such as read only memory (ROM) to store instructions for execution by the processor, and random access memory (RAM) to temporarily store data or hold registry information. ECU 102 may use a micropro...

Abstract

A method for preventing spoofing in an automotive network, the method comprising storing at least one address of a first vehicle electronic control unit and detecting at least one message from a plurality of second electronic control units on a vehicle communications bus, the at least one message having an originating address that matches the at least one address of the electronic control unit and determining that said at least one message was sent by a source other than the electronic control unit; and generating and transmitting a negative acknowledgment (NACK) message to at least one module on the bus in the automotive network, instructing the plurality of second electronic control units to take no action on the at least one message.

Description

technical field [0001] The invention relates to spoofing detection in a motor vehicle network, in particular the invention relates to a method and a system for preventing spoofing in a motor vehicle network and a computer program product for preventing spoofing in a motor vehicle network. Background technique [0002] Modern motor vehicles typically have multiple, eg, as many as seventy, electronic control units (ECUs) for various systems and subsystems. Other ECUs are used in transmissions, airbags, anti-lock brakes / ABS, cruise control, electric power steering, audio systems, power windows, doors, mirror adjustment, batteries and recharging systems for hybrid electric vehicles, and more. Some of these ECUs form independent subsystems, but nevertheless, communication among the ECUs is often necessary. [0003] The Controller Area Network (CAN) bus standard was designed and is well known to allow microcontrollers, such as in ECUs and other devices in vehicles, to communicate...
