Abstract: Systems and techniques are provided for high assurance use cases. For instance, a process can include transmitting, to a secure element, a request to access an applet of the secure element based on a request received from an application executing within a high-level operating system (OS); receiving, from the secure element, a request to retrieve the applet from a portion of a first memory system; retrieving the applet from the first memory system; and providing the applet to the secure element for storage and execution within the secure element.
