Patent abstract

Systems and methods of secure firmware updates on remote vehicles are provided. The system receives a request from a vehicle for an update to vehicle firmware, and identifies a blockchain address for the vehicle. The system generates a session identifier and identifies a firmware update file. The system generates a digital signature based on a combination of the session identifier and a first hash value of the firmware update file. The system provides, for storage in a block at the blockchain address, the digital signature. The system transmits the session identifier to the vehicle. The system transfers the firmware update file to the vehicle. The vehicle verifies the firmware update file using the digital signature retrieved from the block at the blockchain address, a second hash value of the firmware update file received from the data processing system, and the session identifier received from the data processing system.
