METHOD AND SYSTEM FOR MONITORING SECURE APPLICATION EXECUTION EVENTS DURING CONTACTLESS RFID/NFC COMMUNICATION
First Claim
1. A system for reliable monitoring of secure applet events suitable for use in a mobile device, comprising:
- a Near Field Communication (NFC) modem for providing NFC communication, including transaction events, with a NFC reader;
a secure controller (SC) for secure applications execution and secure data processing, monitoring state transitions caused by the transaction events and generating a messaging mechanism via hardware, the SC communicatively coupled to the NCF modem; and
a mobile host communicatively coupled to the SC for receiving event notifications of the state transitions.

Abstract
A system (211) and method (300) for reliable monitoring of secure application execution events is provided. The system can include a Near Field Communication (NFC) modem (140) for communicating transaction events of a secure contactless transaction (358) with a NFC reader (170), a secure controller (200) for monitoring state transitions caused by the transaction events, and a mobile host communicatively coupled to the secure controller for receiving hardware event notifications of the state transitions. The secure controller can generate message using a hardware interrupt to a mobile host based on secure applet state transition monitoring by setting up the events flag such as a Transaction Completion Flag (TCF) (372) into an Events Status Register (232) to identify a status of a secure contactless transactions
