Abstract

A method for operating an external secure unit comprises at least a memory for storing data, a processor for processing the data, at least one interface for receiving data from a communication device or sending them thereto, wherein the communication device comprises at least a memory for storing at least one application program, a processor for processing and executing the application program, at least a first interface for sending data to the external secure unit or receiving them therefrom, at least a second interface for sending data to a transmission network or receiving them therefrom, wherein the method is wherein security-relevant data necessary for executing the application program in the communication device are stored in the external secure unit, and the communication device requests the security-relevant data from the external secure unit for executing the application program.

First claim

1 - 15 . (canceled)

16 . A method for operating an external secure unit which comprises at least
a memory for storing data; a processor for processing the data;
at least one interface for receiving data from a communication device or sending them thereto;
wherein the communication device comprises at least:
a memory for storing at least one application program;
a processor for processing and executing the application program;

at least a first interface for sending data to the external secure unit or receiving them therefrom;
at least a second interface for sending data to a transmission network or receiving them therefrom;
wherein security-relevant data necessary for executing the application program in the communication device are stored in the external secure unit, and the communication device requests the security-relevant data from the external secure unit for executing the application program.

17 . The method according to claim 16 , wherein at least one application program is assigned a security level in dependence on its application.

18 . The method according to claim 16 , wherein data are transferred contactlessly between the communication device and the external secure unit.

19 . The method according to claim 18 , wherein the external secure unit employs as an interface an NFC interface for communication with the communication device.

20 . The method according to claim 16 , wherein the external secure unit employs two- and/or three-dimensionally arranged antennas for communication with the communication device.

21 . The method according to claim 16 , wherein the external secure unit employs a sensor for capturing biometric features.

22 . The method according to claim 16 , wherein as an external secure unit there is employed a finger-ring which consists of at least two components, with an electronic component being inserted into at least one component.

23 . The method according to claim 16 , wherein the finger-ring consists of a strip-shaped material, with the material being shaped into a ring.

24 . The method according to claim 16 , wherein an NFC module is inserted into the ring, with the NFC module being replaceable.

25 . The method according to claim 16 , wherein a mobile telephone is employed as a communication device.

26 . The method according to claim 16 , wherein a mobile radio network is employed as a transmission system.

27 . An external secure unit which is configured to perform a method according to claim 16 .

28 . A method for manufacturing an external secure unit according to claim 27 .

29 . A system consisting of at least one secure unit according to claim 27 and at least one communication device.

30 . The system according to claim 29 , wherein a mobile telephone is employed as a communication device.
