Abstract
A vehicle-to-vehicle communication system includes a controller programmed to digitally sign each of a plurality of basic safety messages (BSMs) using a private key and broadcast each of the BSMs via the transceiver at respective transmit power levels according to a predetermined power level sequence that is defined by one or more values generated from the private key.
Claims20
A vehicle comprising:
- a transceiver for vehicle-to-vehicle communication;
- and
- a controller programmed to, digitally sign each of a plurality of basic safety messages (BSMs) using a private key and broadcast each of the BSMs via the transceiver at respective transmit power levels according to a predetermined power level sequence that is defined by one or more values generated from the private key.
A vehicle system comprising:
- a transceiver;
- and
- a controller programmed to broadcast, via the transceiver, each of a plurality of basic safety messages that are digitally signed using a private key at respective transmit power levels that are defined by a predetermined power level sequence that is defined by one or more values derived from the private key and that defines transmit power levels for consecutive broadcasts to differ by at least a predetermined magnitude.
A method comprising:
- broadcasting, by a vehicle controller, each of a plurality of basic safety messages (BSMs) at respective transmit power levels according to a predetermined power level sequence that is defined by one or more values derived from a private key used for digitally signing the BSMs.
