Security for a wireless ECU vehicle system

摘要

A secure wireless vehicle control system includes a power source installed in a vehicle and a plurality of electronic control units (ECUs) operative to control the operation of components of the vehicle, where each of the ECUs is connected to the power source via electrical wiring, configured with at least a communications unit for receiving security information via the electrical wiring, and also configured with a wireless transceiver operative to use the security information to secure wireless transmission. An ECU includes a wired connection to a vehicle's power source, a communications unit operative to at least receive security information via the wired connection, and a wireless transceiver operative to communicate with at least one other ECU, where the wireless transceiver is configured to use the security information to secure communications with the at least one other ECU. A method for securing wireless communications for an ECU includes receiving security information on a communications unit via a wired connection to a vehicle's power source, and using the security information to secure the wireless communications.

主权项

1. A method for securing wireless communications for a multiplicity of electronic control units (ECUs) installed in a vehicle, the method comprising:
connecting a communication unit on each of said ECUs via electrical wiring to a power source of said vehicle, wherein said ECUs are configured to control one or more of electrical component systems and subsystems of said vehicle; configuring one of said ECUs as a key manager; generating at least one key by said key manager; distributing said at least one key from said key manager via said electrical wiring to other said ECUs from among said multiplicity of ECUs; and applying said distributed at least one key to secure said wireless communications between at least two of said multiplicity of ECUs, wherein said wireless communications are performed via wireless transceivers on said at least two ECUs.
