Complete cloud security solution protects IoT devices from cyber-attack

The OPTIGA™ Trust M tamper-resistant security solution from Infineon is Common Criteria EAL6+ certified. The secure element can be used with any MCU or application processor to enhance the security of IoT designs.

The OPTIGA Trust M from Infineon is a high-end security solution which provides an anchor of trust for connecting IoT devices to the cloud, giving every IoT device its own unique identity. This individual, turnkey solution offers secure, zero-touch onboarding and the high performance needed for quick cloud access.

The OPTIGA Trust M chips and supporting software offer a wide range of security features. In particular, they support common asymmetric cryptography algorithms including: 

  • RSA® 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 development process is certified according to the security standard IEC 62443-4-1 for industrial automation and control systems, acting as an enabler to achieve component-level certification according to IEC 62443-4-2.

The OPTIGA Trust M security solution is specified in two operating-temperature ranges:

  • SLS32AIA010MK at a standard temperature range of -25°C to 85°C for most commercial implementations
  • SLS32AIA010ML at an extended temperature range of -40°C to 105°C for harsh industrial environments

The OPTIGA Trust M chip is supplied in a USON-10 package that has a footprint of 3 mm x 3 mm.
