Trust M Click Board™

Product Code: MIKROE-4236

How Does The Trust M Click Board™ Work? As embedded systems (e.g. IoT devices) are increasingly gaining the attention of attackers, the Trust M Click Board™ offers the OPTIGA™ Trust M1 from Infineon as a turnkey security solution for industrial automation systems, smart homes, consumer devices and medical devices. This high-end security controller comes with full system integration support for easy and cost-effective deployment of high-end security for your assets. The Trust M Click Board™ comes with up to 10kB user memory that can be used to store X.509 certificates and data. OPTIGA™ Trust M1 is based on Common Criteria (CC) Certified EAL6+ (high) hardware enabling it to prevent physical attacks on the device itself and providing high assurance that the keys or arbitrary data stored cannot be accessed by an unauthorized entity. All communication is done through I2C bus which supports a highspeed I2C communication interface of up to 1MHz (FM+). Trust M Click also features two FETs for disconnecting/connecting power to IC using EN pin on mikroBUS™ which allows it to go to hibernation.

During chip production, unique asymmetric keys (private and public) are generated. The public key is signed by customer specific CA and the resulting X.509 certificate issued is securely stored in the OPTIGA™ Trust M1. Special measures are taken to prevent the leakage and modification of private key material at the Common Criteria Certified production site. All of this features available on the Trust M Click Board™ makes it perfect solution for industrial automation systems, smart homes and consumer devices in broad range of use cases necessary to protect the authenticity, integrity and confidentiality in your device: mutual authentication, secured communication, data store protection, life-cycle management, secured updates, and also platform integrity protection.
