Embodiment Construction

[0015]Following below are more detailed descriptions of various concepts related to, and implementations of, methods, apparatuses, and systems of network-based path generation for a vehicle controller. The various concepts introduced above and discussed in greater detail below may be implemented in any of numerous ways.

[0016]The present disclosure is directed to systems and methods of secure firmware updates for remote vehicles. Vehicles such as automobiles can include numerous digital hardware components that run or execute firmware. The digital hardware components can perform critical functions of the vehicle or be integral to critical vehicle systems. The firmware run by the digital hardware components can be updated periodically to improve the functionality of the digital hardware components. As errors, faults, issues, or improvements are identified for the hardware component, a server can transfer a firmware update for the component. However, due to the vehicle being remote fro...

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.

Description
