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.
Features of the shield board include:
- Pre-provisioned TLS security certificates
- CC EAL 6+ certified hardware
- Qwiic compatible
- I2C interface with shielded connection
- Cryptographic toolbox
- Supports multiple cryptographic algorithms: ECC, RSA, AES, HMAC, HKDF, TLS PRF
