Secure firmware updates for connected industrial devices
Signed and encrypted firmware updates, verified on the device, whether the update arrives over the air or over a wired connection.
- Over the air or wired
- Verified on the device
- Bad updates are stopped
What we offer
Security as a top priority
Proekspert helps device manufacturers to prepare for the EU Cyber Resilience Act.
We develop secure firmware update solutions that ensure the device software is protected no matter how the update package is delivered to the device: over-the-air (OTA) or wired medium.
WHY THIS SOLUTION
Three scenarios to use secure firmware update solution
Scenario 1
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.
Scenario 2
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.
Scenario 3
Protect device firmware against industrial espionage
Firmware update packages can be encrypted for each device individually, so an intercepted package can’t be read or reused.
Common risks when updating device software
Unverified sources
Offline devices cannot verify if a specific firmware image is coming from an authentic source.
Lack of trained specialists
Updating device software manually on a site is costly for maintenance service providers.
Malicious users
Malicious users may tamper with a device by spoofing it or replacing data packages sent to the server.
Unintended features
A wrong firmware version may ruin a user experience, break important features, or even brick the device.

How it works
Secure FW update from a cloud service
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.
