Tamper-resistant security controller to safeguard microcontrollers in smart buildings offered by Infineon

The discrete Secure Element can integrate into any microcontroller-based design to enhance security and handle several product protocols at once.

MUNICH – Infineon Technologies AG in Munich is introducing the OPTIGA Trust M MTR tamper-resistant security controller to facilitate integration of the Matter standard and security features into smart home and smart building devices.

The number of smart home devices will double by 2030, reaching about 1.7 billion worldwide, experts say. All these devices have to be able to connect securely and reliably with each other and with different systems in smart buildings.

The Matter protocol supports uniform security and privacy measures for the smart home. The tamper-resistant security controller can perform security-related functions and protect sensitive data and cryptographic operations.

As a discrete Secure Element, OPTIGA Trust M MTR can integrate into any microcontroller-based design to enhance security and handle several product protocols simultaneously.

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 personalized DAC injection at a later point right up until the start of device production.

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.

Samples of OPTIGA Trust M MTR are available now together with the OPTIGA Trust M MTR Shield for easy evaluation and design-in. For more information contact Infineon online at www.infineon.com.
