Publication number: 20250233759Abstract: Embodiments described herein provide techniques for securely validating firmware on a device using certificates and providing a mechanism for deprecating select certificates when a traditional certificate authority is unavailable or otherwise cannot be used. When a first firmware package is installed on the device, a first certificate in a first secure memory location is associated with an active status. Responsive to validation and installation of a second firmware package on the device, a second certificate in a second secure memory location on the device is associated with an active status. During a boot-up operation on the device, embodiments determine to use the second certificate to validate the second firmware package by starting at a predefined secure memory location and scanning backwards until a status of active is identified. The second firmware package on the device is then validated using the second certificate.Type: ApplicationFiled: January 11, 2024Publication date: July 17, 2025Applicant: Schneider Electric USA, Inc.Inventor: Michael Pyle
