Infineon makes it easier to add Matter and security to smart home devices

2 mins read

Infineon Technologies has introduced the OPTIGA Trust M MTR, a Matter-certified Secure Element and the latest configuration of Infineon’s OPTIGA Trust M.

The announcement comes at a time of increasing connectivity and the growing popularity of the Internet of Things and the demand to simplify interoperability across connected devices while enhancing their security and reliability.

The Matter standard 1 was created precisely to address this and the OPTIGA Trust M MTR has been designed to facilitate integration of the Matter standard and security features into smart home and smart building devices.

According to ABI Research forecasts, the number of smart home devices will double by 2030, reaching about 1.7 billion worldwide and these devices will need to be connected securely and reliably with each other and with other different smart home ecosystems.

The Matter standard facilitates smooth interoperability across connected devices even from different companies and the Matter protocol defines a set of principles that support uniform security and privacy measures for the smart home.

“When we designed the Matter protocol in the Connectivity Standards Alliance, we were committed to building in strong security,” said Steve Hanna, Distinguished Engineer at Infineon and leader of the standards teams that defined Matter’s security. “That’s why Matter brings new security features to the smart home, some of which were challenging for IoT product designers. Infineon’s OPTIGA Trust M MTR addresses those challenges head-on so that now it can be even easier to build a Matter product.”

The tamper-resistant security controller can be easily integrated into a system to perform security-related functions and provide a high level of protection for sensitive data and cryptographic operations.

As a discrete Secure Element, OPTIGA Trust M MTR can be integrated into any MCU-based design to enhance security and handle multiple product protocols simultaneously. This gives original equipment manufacturers greater flexibility and allows faster time to market.

According to the Matter protocol, every smart home device must have a Device Attestation Certificate (DAC), containing the Product ID (PID) and the Vendor ID (VID), to verify the authenticity and trustworthiness of each device commissioned in the Matter ecosystem. With OPTIGA Trust M MTR, the PID no longer needs to be defined in advance when the reel is ordered or manufactured. Instead, each device receives a personalised DAC injection at a later point right up until the start of device production. This gives device manufacturers more flexibility in creating multiple product variants of smart home devices.

OPTIGA Trust M MTR Secure Elements are pre-provisioned at a Common Criteria-certified Infineon facility. The batch of Secure Elements on a reel is shipped with an associated barcode. The customer claims ownership of these chips on the IoT portal of Infineon partner Kudelski IoT by scanning the barcode. Kudelski IoT will enable the download of production DACs corresponding to the vendor and the product.

Finally, the personalised DAC is transferred to the OPTIGA Trust M MTR at the factory level.

Samples of OPTIGA Trust M MTR are available now together with the OPTIGA Trust M MTR Shield for easy evaluation and design-in. Availability for the broad market will begin in March 2024.
