Infineon — OPTIGA TRUST M MTR Secure Element

The existing OPTIGA Trust M secure element from Infineon is already widely used to provide an anchor of trust for connecting IoT devices to the cloud, giving every IoT device its own unique identity. A turnkey solution, the OPTIGA Trust M chip offers secure, zero-touch onboarding and the high performance needed for quick cloud access. 

Now Infineon has extended the secure element offering with a Matter-specific provisioning service, to provide a fast and simple solution for embedding secure Matter networking capability into any IoT device.  

The OPTIGA Trust M MTR solution is certified to be compliant with the Matter standard specifications, and works with any microcontroller or system-on-chip. Supported by its partner Kudelski IoT, Infineon offers late-stage, personalized device attestation certificate (DAC) injection to give OEMs the flexibility to update DACs until the start of production. 

The OPTIGA Trust M MTR chip and its supporting software offer a wide range of security features. In particular, this solution supports common asymmetric cryptography algorithms including:  

• RSA® cryptography up to 2048  

• AES key up to 256, HMAC up to SHA512  

• TLS v1.2 PRF and HKDF up to SHA512 

The turnkey set-up with full system integration minimizes the design, integration and deployment effort required of product manufacturers. The OPTIGA Trust M MTR development process is certified according to the security standard IEC 62443-4-1, acting as an enabler to achieve component-level certification according to IEC 62443-4-2. 

The OPTIGA Trust M MTR chip is supplied in a USON-10 package that has a footprint of 3 mm x 3 mm. It can be ordered with the part numbers SLS32AIA010MMUSON10XTMA2 or SLS32AIA010MMUSON10XTMA1.
