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, there is support for common asymmetric cryptography algorithms including:
The turnkey set-up with full system integration minimizes the design, integration and deployment effort required from 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 is specified in two operating-temperature ranges:
The OPTIGA Trust M chip is supplied in a USON-10 package that has a footprint of 3 mm x 3 mm.
TRUSTMV3SHIELDTOBO1 TRUST-M-SHIELD
The OPTIGA™ Trust M Shield provides a hardware platform for assessing the OPTIGA™ Trust M security solution in embedded security applications. The shield is designed for use with compatible microcontroller development boards and exposes the OPTIGA Trust M interface over I2C, allowing evaluation of secured key storage, cryptographic operations, and device authentication workflows.
The board supports testing of asymmetric and symmetric cryptographic functions, secured certificate handling, and protected communication channels used in IoT and industrial systems. It allows engineers to evaluate hardware root of trust integration without modifying an existing application board design.
The evaluation shield is suitable for examining manufacturing-time provisioning, device-to-cloud authentication, and lifecycle security use cases. It supports interaction with Infineon software libraries and middleware for secured communication, enabling validation of OPTIGA™ Trust M behavior during development, onboarding, and field operation scenarios.
