SECURE FIRMWARE UPDATE THROUGH A PREDEFINED SERVER - A simplified explanation of the abstract
This abstract first appeared for US patent application 18542440 titled 'SECURE FIRMWARE UPDATE THROUGH A PREDEFINED SERVER
Simplified Explanation
The disclosed embodiments relate to securely booting firmware images. In one embodiment, a method is disclosed comprising receiving a firmware update; validating a signature associated with the firmware update; copying an existing firmware image to an archive location, the archive location storing a plurality of firmware images sorted by version identifiers; booting and executing the firmware update; and replacing the firmware update with the existing firmware image stored in the archive location upon detecting an error while booting the firmware update.
- Explanation of the patent/innovation:
- Receiving and validating firmware updates securely - Archiving existing firmware images for backup - Booting and executing firmware updates - Reverting to a previous firmware image in case of errors during booting
- Potential applications of this technology:
- Secure booting of firmware in IoT devices - Updating firmware in embedded systems - Enhancing cybersecurity in electronic devices
- Problems solved by this technology:
- Ensuring the authenticity of firmware updates - Providing a backup mechanism for firmware images - Preventing system failures due to errors in firmware updates
- Benefits of this technology:

Original Abstract Submitted
The disclosed embodiments relate to securely booting firmware images. In one embodiment, a method is disclosed comprising receiving, by a memory device, a firmware update; validating, by the memory device, a signature associated with the firmware update; copying, by the memory device, an existing firmware image to an archive location, the archive location storing a plurality of firmware images sorted by version identifiers; booting, by the memory device, and executing the firmware update; and replacing, by the memory device, the firmware update with the existing firmware image stored in the archive location upon detecting an error while booting the firmware update.
