Abstract:
1. A method for using an embedded Secure Element (eSE) of a mobile device to execute a Near Field Communication (NFC) application stored in a non-volatile memory external to the eSE, the method comprising: loading code and state data associated with the NFC application from the non-volatile memory into the eSE; authenticating the code and the state data loaded from the non-volatile memory; after authenticating the code and the state data, executing the code in the eSE to exchange data with a contactless communication device using a NFC controller; incrementing a dedicated count value corresponding to the NFC application in response to the state data being updated based on the data exchanged with the contactless communication device; and maintaining the dedicated count value in a bundle of dedicated count values protected by a replay counter in the eSE.
