摘要： Method and apparatus are disclosed for controller area network message authentication. An example disclosed vehicle includes a data bus and a first control unit communicatively coupled to the data bus. The example first control unit generates a secured message by (a) calculating a message authentication code, (b) truncating the message authentication code, (c) truncating a freshness value used to generate the message authentication code, and (d) placing portions of the truncated message authentication code and the truncated freshness value in separate portions of the secured message.

摘要： Systems and methods are disclosed for private vehicle-to-vehicle communication. An example disclosed vehicle communication system includes sensors to monitor a target vehicle, and a controller. The example controller generates a pseudo-anonymous identifier based on an identifier and an attribute of the target vehicle. Additionally, the controller broadcasts a first message including the pseudo-anonymous identifier, a random number, and a public key. In response to receiving a second message including the identifier and the random number, the example controller broadcasts a third message encrypted with a symmetric key included in the second message.

摘要： A vehicle includes a rail-mounted component. The rail-mounted component can be equipped with one or more restraints. A restraint monitoring system monitors the one or more restraints. The restraint monitoring system includes a restraint control module and a rail-mounted component control module. The rail-mounted component control module can include a restraint deployment loop and a restraint diagnostic loop for relaying restraint deployment signals and restraint diagnostic signals, respectively, between the restraint control module and the rail-mounted component control module.

摘要： A first electronic control unit (ECU) is in communication with a second ECU over a vehicle bus. The first ECU is configured to generate functional safety values and security protection values for a message, validate the security protection values for the message, and send the message to the second ECU including the security protection values but not the functional safety values.

摘要： A system includes a processor configured to wirelessly broadcast a message obtained from a first originating vehicle BUS or controller, following a determination that the message was on a pre-approved list for broadcast and having encrypted the message utilizing a temporary random key generated for a message session. The system may include vehicle controllers, a gateway module, and vehicle BUSSES connecting the system controllers to the gateway module. The gateway module may include a memory storing a list of pre-approved message types and corresponding source types, and a processor configured to receive a message from one of the vehicle controllers over one of the vehicle BUSSES to determine if a message type and source type of the received message matches an element of the list.
