Systems and methods for automatically updating system firmware
| DWPI Title: FaaS system for performing secure firmware updating for motor vehicle, has z-engine circuitry for receiving firmware for particular user device of set of user devices and circuitry receives non-repeating input data, and retrieves hardware digital profile of particular user device |
| Abstract: In an approach to secure firmware updating, a system comprises: one or more user devices, each of the one or more user devices having one or more firmware modules; one or more computing devices; a digital signature repository; and a z-engine circuitry. The z-engine circuitry is configured to: receive firmware for a particular user device of the one or more user devices; receive a non-repeating input data; retrieve a hardware digital profile of the particular user device from the digital signature repository; process the non-repeating input data with the hardware digital profile to generate a unique result; perform a hash operation on the unique result to generate an encryption key; encrypt the firmware for the particular user device with the encryption key; and send the encrypted firmware to the particular user device. |
| Use: Firmware as a Service (FaaS) system for performing secure firmware updating for a motor vehicle. Can also be used in medical equipment or critical infrastructure. |
| Advantage: The systems and methods provides to securely distribute firmware upgrades to hardware devices using an Over-the-air (OTA) mechanism to avoid a user having to bring the device in person to a service center or dispatch a technician for a service call. |
| Novelty: The system (110) has a z-engine circuitry (116,134,144) for receiving a firmware for a particular user device (130,140) of a set of user devices. The circuitry receives a non-repeating input data e.g. Unix (RTM: Computer operating system) timestamp, and retrieves a hardware digital profile of the particular user device from a digital signature repository (118,136,146). The circuitry processes the non-repeating input data with the hardware digital profile to generate a unique result, and performs a hash operation i.e. secure hash algorithm (SHA), on the unique result to generate an encryption key. The circuit encrypts the firmware for the particular user device with the encryption key, and sends the encrypted firmware to the particular user device. |
