A secure firmware update solution
Scale your product reach
Innovate with balanced product cost
Reduce product maintenance costs
Proekspert has developed a secure firmware update solution to be used in two case scenarios. With the goals of long life and high uptime expectancy, some device maintenance and upgrading can be accomplished through software updates.
Case 1. Licensing device firmware
Device makers need control over software that is run on their devices. Proekspert has developed a hardware-level license verification solution to determine if an end-user is eligible for software updates or new features.
Case 2. Preventing unintended device firmware updates
Updating devices over the internet or on-site by a technician poses risks of malicious usage and simple human error and may render a device inoperable, causing enormous expense, especially when the device is in a difficult to reach or remote location. To give device manufacturers more control in the software update process, Proekspert has developed a hardware-level device firmware authenticity validation solution.
Common risks when updating device software
How it works
Proekspert’s firmware authenticity verification software uses a crypto processor chip (TPM) integrated with a device’s motherboard to automatically verify an update file signature and/or decrypt a previously encrypted firmware update package. Each TPM is unique, so on the device software development side the firmware is signed or encrypted for devices one by one. When a device updater discovers firmware with an incorrect signature or encryption, the update process halts without altering already installed software.
