Abstract: Embodiments of the present disclosure are directed to methods and systems for providing secure over-the-air firmware updates to one or more vehicles. More specifically, the present disclosure describes applying to firmware images distributed to one or more vehicles encryption that is unique to each update version. The encryption is also unique to each vehicle receiving the update. Embodiments of the present disclosure can also include determining and verifying the integrity of an available OTA firmware update prior to authorizing installation of the firmware update in a vehicle.

Abstract: When operating these different environments, the infrastructure of and around a vehicle should be secure to prevent unauthorized and possibly malicious access to the vehicle and the systems therein. To obtain this security, the various systems and components of the vehicle can utilize certificates to authenticate and authorize users as well as equipment and/or components interfacing with the vehicle. According to one embodiment, a portable compute device or tool with internet access can be used in any one or more environments to transport certificates used to support secure connectivity for vehicle systems in a state where the vehicle may or may not have immediate internet access. This tool can also provide various service functions in these different environments. These functions can include performing diagnostics, updating firmware images, collecting log and other data from the vehicle, etc.
