La carte Click Board™ de Plug&Trust est une carte complémentaire compacte qui contient une solution d'élément sécurisé IoT prête à l'emploi. Cette carte est dotée de l'élément sécurisé IC SE050C NXP, qui fournit une racine de confiance au niveau du circuit intégré et offre à un système IoT une capacité de sécurité de pointe, de la périphérie au cloud. La SE050C permet de stocker et de provisionner en toute sécurité les informations d'identification et d'effectuer des opérations cryptographiques pour les fonctions de communication et de contrôle critiques pour la sécurité. Elle dispose d'une certification de sécurité indépendante Common Criteria EAL 6+ jusqu'au niveau du système d'exploitation et prend en charge les algorithmes cryptographiques asymétriques RSA et ECC avec une longueur de clé élevée et des courbes ECC à l'épreuve du temps, protégeant ainsi la SE050C même contre les scénarios d'attaque sophistiqués non invasifs et invasifs. Cette carte Click Board™ convient aux cas d'utilisation de sécurité IoT tels que la connexion sécurisée aux clouds publics/privés, l'authentification d'appareil à appareil, la protection des données des capteurs, etc.
Cliquez sur Plug&Trust est pris en charge par une bibliothèque compatible mikroSDK, qui comprend des fonctions qui simplifient le développement logiciel. Cette Click Board™ est un produit entièrement testé, prêt à être utilisé sur un système équipé du socket mikroBUS™.
How Does the Plug&Trust Click Board™ work?
The Plug&Trust Click Board™, as its foundation, uses the SE050C, a ready-to-use IoT secure element solution that provides a root of trust at the IC level, and it gives an IoT system state-of-the-art, edge-to-cloud security capability from NXP Semiconductors. It is designed to be used as a part of an IoT system; works as an auxiliary security device attached to a host MCU. It offers enhanced Common Criteria EAL 6+ security certification up to the OS level and supports both RSA and ECC asymmetric cryptographic algorithms with high key length and future proof ECC curves. The latest security measures protect the IC against sophisticated non-invasive and invasive attack scenarios.
The SE050C is a turnkey solution that comes with JavaCard operating system and an applet optimized for IoT security use cases, pre-installed. To support scalability while servicing the broadest range of use cases in IoT applications, the SE050C is available in different pin-to-pin compatible configurations, including versions with support for sensors directly attached to the device, the I2C Controller, or contactless interface.
The Plug&Trust Click Board™ communicates with MCU using the standard I2C 2-Wire interface, where the host controller represents the Controller and the Click board being the Target. Besides the mandatory connection to the host controller, this Click board™ can optionally be connected to a sensor node or similar element through separate I2C interface pins located on the 1x4 male header labelled as I2C Master. In this case, the SE050C device is the Controller device, and the sensor node represents the Target.
This Click board™ also offers a choice for the user to select the appropriate I2C communication speed, selected by onboard SMD jumpers labelled as I2C SPEED to a proper position marked as 400Kb and 3.4Mb. Note that all the jumpers must be lined to the same side, or else the Click board™ may become unresponsive. On the other side, the Shutdown pin, labelled as EN and routed to the CS pin of the mikroBUS™ socket, optimizes power consumption and is used for power on/off purposes, while the RST pin has no functionality in I2C Mode. Also, this Click board has an onboard antenna, providing a wireless interface to an external device like a smartphone, connected via a switch labelled as ANTENNA with SE050C allowing the activation of the antenna itself by setting it to the appropriate ON or OFF position.
The Plug&Trust Click Board™ can be operated only with a 3.3V logic voltage level. The board must perform appropriate logic voltage level conversion before use with MCUs with different logic levels. However, the Click board™ comes equipped with a library containing functions and an example code that can be used, as a reference, for further development.
