NEAR FIELD COMMUNICATION EQUIPPED DEVICE

摘要

The present application relates to a near field communication (NFC) equipped device (40) such as a mobile telephone. The device (40) includes an NFC controller (42) for controlling NFC operations of the device and a secure element (48) for NFC applications and sensitive data. The secure element (48) includes non-volatile memory which is used by the device (40) to store non-volatile NFC data. The non-volatile NFC data is transferred between the secure element (48) and the NFC controller (42) by means of a single wire protocol interface and dedicated proprietary gates of a host controller interface, which dedicated gates are used for transferring the non-volatile NFC data to the secure element memory and retrieving the non-volatile NFC data from the secure element memory. Using the secure element memory in this way obviates the need for non-volatile memory associated with the NFC controller.

主权项

1. A secure element for use in an NFC equipped device, wherein the secure element is configured to defer booting up its main operating system for a period sufficient to permit retrieval of non-volatile data from the secure element within a predetermined time period.
