Abstract

A method for managing data communication between a communication device (102) and another device (112) in a communication network, comprises providing (500) data for transmission by the communication device (102), and controlling by at least one secure management element (300, 304) operating in a secure environment (218) in the communication device the transmission of the provided data by the communication device so as to manage data transmitted by the communication device. The step of controlling may include at least one of controlling an amount of data transmitted, controlling a time of transmission of data and controlling a periodicity of transmission of data. A communication device and a method of managing data received by a communication device are also described.

Claims

1. A method for managing data communication between a communication device and another device in a communication network, comprising:

providing data for transmission by the communication device;

controlling by at least one secure management element operating in a secure environment in the communication device the transmission of the provided data by the communication device so as to manage data transmitted by the communication device.

2. The method of claim 1, wherein controlling includes controlling an amount of data transmitted, controlling a time of transmission of data and control a periodicity for transmission of data.

3. The method of claim 1, wherein the at least one secure management element includes a secure code element operating in the secure environment and wherein controlling comprises:

providing to the secure code element in the secure environment a secure code;

and wherein the method further comprises in the communication device, operating on the provided data using the secure code to provide modified data representing valid data to another device; and

transmitting by the communication device modified data to the another device so as to manage data transmissions by the communication device using the secure code.

4. The method of claim 3, wherein the secure code element includes a keystream generator and the secure code includes a keystream and wherein providing a secure code comprises generating a keystream by the keystream generator and wherein operating on includes combining the keystream with the provided data to provide ciphered data and transmitting comprises transmitting ciphered data.

5. The method of claim 4, wherein providing a secure code comprises providing at least one parameter to the secure code element, the at least one parameter identifying a desired character for data to be transmitted and generating the secure code in the secure code element using the at least one parameter, wherein the at least one parameter determines the number of bits in the keystream.

6. The method of claim 1, wherein controlling further comprises preventing by the at least one secure management element further transmissions of data controlled by the at least one secure management element when the data transmitted by the communication device reaches a limit.

7. The method of claim 6, wherein the limit includes a maximum amount of data or a maximum time limit for transmission.

8. The method of claim 6, wherein the limit is stored in the secure environment.

9. The method of claim 8, further comprising exchanging authentication messages between the communication network and the communication device for updating securely the limit in the control element.

10. The method of claim 3, wherein the secure code is a cipher key and operating on comprises ciphering the provided data in the secure environment using the cipher key to provide ciphered data and transmitting comprises transmitting ciphered data.

11. A method for managing data communication between a communication device and another device in a communication network, comprising:

receiving data at the communication device;

determining by an element in a secure environment in the communication device whether the received data is valid;

providing to a secure code element in the secure environment a secure code and when the received data is determined valid data, operating on the received data using the secure code to provide data for further processing in the communication device so as to manage data received by the communication device using the secure code.

12. A communication device for communicating with another device in a communication network, the communication device comprising:

a transmitter section for transmitting data;

at least one secure management element arranged to operate in a secure environment in the communication device for controlling the transmission of data provided to the communication device so as to manage data transmitted by the transmitter.

13. The communication device of claim 12, wherein the at least one secure management element is arranged to at least one of control an amount of data transmitted, control a time of transmission of data and control a periodicity of transmission.

14. The communication device of claim 12, wherein the at least one secure management element includes a secure code element arranged to operate in the secure environment and wherein the secure code element is arranged to be provided with a secure code,

wherein the communication device further comprises a data processing element for operating on the provided data using the secure code to provide modified data representing valid data to another device;

and

wherein the transmitter is arranged to transmit modified data to the another device.

15. The communication device of claim 14, wherein the secure code element includes a keystream generator and the secure code includes a keystream generated by the keystream generator and wherein the data processing element is arranged to combine the keystream with the provided data to provide ciphered data for transmission by the transmitter.

16. The communication device of claim 12, wherein the at least one secure management element further comprises a control element arranged to operate in the secure environment for preventing further transmissions of data controlled by the at least one secure management element when the data transmitted by the communication device reaches a limit.

17. The communication device of claim 16, wherein the limit includes a maximum amount of data or a maximum time limit for transmission.

18. The communication device of claim 17, wherein the maximum limit is stored in the control element.
