A secure firmware update solution

Scale your product reach

Innovate with balanced product cost

Reduce product maintenance costs

Proekspert develops 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.

The secure firmware update solution is used in two case scenarios.

S1. 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.

S2. 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.

Common risks when updating device software

Unverified sources

Updating offline device software locally by a specialist or end-user requires confidence the updater has the specific firmware image coming from an authentic source which is built for the specific device.

Lack of trained specialists

Updating device software manually on site is costly for maintenance service providers (trained personnel, travel costs, complex on-site conditions, etc.).

Malicious users

Enabling remote update functionality over the internet exposes a device to malicious users who may tamper with the device by altering the original firmware update package.

Unintended features

Installing a software update can enable or disable features that were not meant for a specific user type or machine model. This may ruin the user experience or break important features.

Key features and benefits of our solution

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.

Secure FW update from a cloud service
