Abstract

A radio communication device is described comprising: a transceiver circuit configured to communicate wirelessly with another device; a tamper-proof circuit connected to the transceiver circuit; and a processor connected to the tamper-proof circuit and configured to exchange data with the transceiver circuit via the tamper-proof circuit.

Claims

1. A device, comprising:

an NFC controller, comprising;

a transceiver circuit configured to wirelessly receive first data from a device;

wherein the NFC controller is further configured to provide the first data, without having a direct physical signaling between the transceiver circuit and an application processor circuit, in the form of second data to the application processor circuit via a secure element, where a secure function is performed on the first data to produce the second data;

the secure element operably coupled to the NFC controller via a first interface;

the application processor circuit operably coupled to the secure element via a second interface; and

an antenna coupled to the NFC controller.

2. The device of claim 1, wherein the NFC controller further comprises:

one or more elements from a group of elements consisting of;

an embedded secure element;

a Universal Integrated Circuit Card; and

a Subscriber Identity Module.

3. The device of claim 2, wherein the embedded secure element is an embedded Subscriber Identity Module.

4. The device of claim 1, wherein the NFC controller is integrated in a System-on-Chip or an Integrated Circuit.

5. The device of claim 1, wherein the NFC controller is configured to provide the first data to the secure element via a single wire protocol interface.

6. A device, comprising:

an NFC controller, comprising;

a transceiver circuit configured to wirelessly receive first data from a device;

wherein the transceiver circuit is configured to communicate with an application processor circuit via a secure element without having a direct physical signaling between the transceiver circuit and the application processor circuit;

wherein the NFC controller is further configured to provide the first data to the secure element to provide authentication;

the secure element operably coupled to the NFC controller via a first interface;

the application processor circuit operably coupled to the secure element via a second interface; and

an antenna coupled to the NFC controller.

7. The device of claim 6, wherein the NFC controller further comprises:

one or more elements from a group of elements consisting of;

an embedded secure element;

a Universal Integrated Circuit Card; and

a Subscriber Identity Module.

8. The device of claim 7, wherein the embedded secure element is an embedded Subscriber Identity Module.

9. The device of claim 6, wherein the NFC controller is integrated in a System-on-Chip or an Integrated Circuit.

10. The device of claim 6, wherein the NFC controller is configured to provide the first data to the secure element via a single wire protocol interface.

11. A device, comprising:

an NFC controller, comprising;

a transceiver circuit configured to wirelessly receive first data from a device;

wherein the NFC controller is further configured to communicate with an application processor circuit via a secure element, and to directly and exclusively send the sensitive data the secure element without exposing the sensitive data directly to the application processor circuit;

the secure element operably coupled to the NFC controller via a first interface;

the application processor circuit operably coupled to the secure element via a second interface; and

an antenna coupled to the NFC controller.

12. The device of claim 11, wherein the NFC controller further comprises:

one or more elements from a group of elements consisting of;

an embedded secure element;

a Universal Integrated Circuit Card; and

a Subscriber Identity Module.

13. The device of claim 12, wherein the embedded secure element is an embedded Subscriber Identity Module.

14. The device of claim 11, wherein the NFC controller is integrated in a System-on-Chip or an Integrated Circuit.

15. The device of claim 11, wherein the NFC controller is configured to send the sensitive data to the secure element via a single wire protocol interface.
