Proekspert helps device manufacturers to prepare for upcoming 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.

Register here for free meeting where we help you to discover how to improve your device security.

The secure firmware update solution is used in three 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.

S3. Protect device firmware for industrial espionage

Common risks when updating device software

Unverified sources

Offline devices cannot verify if the specific firmware image is coming from an authentic source

Lack of trained specialists

Updating device software manually on site is costly for maintenance service providers

Malicious users

Malicious users may tamper with the device by altering the original firmware update package

Unintended features

Wrong firmware version may ruin the user experience or break important features

Key features and benefits of our solution

Enabling secure remote updates Over-the-Air and via Ethernet

Preventing human errors by protecting a device against manual invalid FW updates online and offline

Protecting device software against malicious usage and network attack

Enabling device-level software licenses

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.
