Das SE051 Plug&Trust Click Board™ ist eine kompakte Zusatzplatine, die eine gebrauchsfertige IoT-Sicherheitslösung darstellt. Diese Platine verfügt über das SE051C2, eine aktualisierbare Erweiterung des EdgeLock™ SE050 von NXP Semiconductor, das bewährte, nach CC EAL 6+ zertifizierte Sicherheit mit AVA_VAN.5 bis zur Betriebssystemebene bietet. Es wurde für die neuesten IoT-Sicherheitsanforderungen entwickelt und ermöglicht die sichere Speicherung und Bereitstellung von Anmeldeinformationen durch die Durchführung kryptografischer Vorgänge, wodurch Edge-to-Cloud-Sicherheitsfunktionen sofort einsatzbereit sind. Es bietet außerdem Upgrade-Funktionalität für das IoT-Applet unter Beibehaltung der Anmeldeinformationen auf dem Gerät sowie die Möglichkeit zur Neukonfiguration. Dieses Click Board™ ist vielseitig einsetzbar in IoT-Sicherheitsanwendungsfällen wie sicherer Verbindung zu öffentlichen/privaten Clouds, Gerät-zu-Gerät-Authentifizierung oder Schutz von Sensordaten, Bescheinigung und Nachweis der Geräteherkunft und vielem mehr.
Das SE051 Plug&Trust Click Board™ wird von einer mikroSDK-kompatiblen Bibliothek unterstützt, die Funktionen enthält, die die Softwareentwicklung vereinfachen. Dieses Click Board™ ist ein gründlich getestetes Produkt und kann auf einem System verwendet werden, das mit der mikroBUS™-Buchse ausgestattet ist.
How Does The SE051 Plug&Trust Click Board™ Work?
The SE051 Plug&Trust Click Board™ is based on the SE051C2, a ready-to-use IoT secure element solution from NXP Semiconductor, providing a root of trust at the IC level and giving an IoT system state-of-the-art, edge-to-cloud security capability right out of the box. It has an independent Common Criteria EAL 6+ security certification up to OS level. It supports both RSA & ECC asymmetric cryptographic algorithms with high key length and future-proof ECC curves. Designed for the latest IoT security requirements, it allows for securely storing, provisioning credentials, and performing cryptographic operations for security-critical communication and control functions.
The SE051C2 represents a turnkey solution with a Java Card operating system and an updatable pre-installed applet optimized for IoT security use cases. Alongside the updatable IoT applet, it also possesses SEMS Lite and a PERSO applet that provides upgradability of the IoT applet while preserving on-device credentials and the possibility to reconfigure the SE051 device. The SEMS Lite represents a capability based on a subset of GlobalPlatform's Secure Element Management Service (SEMS), optimized for IoT use cases.
The SE051 Plug&Trust Click Board™ communicates with MCU using the standard I2C 2-Wire interface. 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 on the 1x4 male header labelled I2C Master. In this case, the SE051C2 device is the Controller device, and the sensor node represents the Target. This board also allows the user to select the appropriate I2C communication speed by onboard SMD jumpers labelled as I2C SPEED to a proper position marked as 400Kb and 1Mb. Note that all the jumpers must be lined to the same side, or else the Click board™ may become unresponsive.
Besides, the SE051C2 provides a special power-saving mode offering maximum power saving. The way of activation of this mode is realized with the onboard switch marked as ENA SEL. In this way, Power-Saving Mode can be activated via the EN pin, routed to the CS pin of the mikroBUS™ socket, primarily by placing the switch to the EN position and then pulling the EN pin to a logic zero level. By placing the switch in the second position marked as ON, the SE051C2 is in normal operation mode. The RST pin has no functionality in I2C Mode. It can only be used as an external reset source if the ISO7816 interface is enabled (not in generic SE051 configurations).
Also, the SE051 Plug&Trust Click Board™ has an onboard antenna, providing a wireless interface (ISO14443) to an external device like a smartphone, connected via a switch labelled as ANTENNA with SE051C2 allowing the activation of the antenna itself by setting it to the appropriate ON or OFF position.
The SE051 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 using 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.
