Abstract
A runtime environment executing on a card computing device may handle communication of APDU messages received by a card computing device according to the HCI communication protocol over an APDU gate. APDU messages may be encapsulated and transmitted within multiple HCI messages and the runtime environment may be configured to extract and verify the APDU messages from within the received HCI messages, according to some embodiments. The runtime environment may be configured to receive commands to open an APDU pipe, manage multiple open pipes, receive incoming HCI commands, and route the encapsulated APDU messages to an appropriate application executing within the card computing device. The runtime environment may also be configured to receive APDU messages from the application, encapsulate the APDU messages within HCI messages and send the HCI messages over the same APDU pipe.
