Abstract

An electronic module that includes means for determining an operating system targeted by a message received by a transmitter-receiver of an electronic device, from among at least a Rich-OS operating system and a trusted operating system executed on a chipset of the electronic device, so that the message becomes accessible to the targeted operating system. The determining means may be set in operation in response to receipt of the message by the transmitter-receiver.

Claims

1. An electronic module comprising:

means for determining an operating system targeted by a message received by a transmitter-receiver of an electronic device, from among at least a Rich-OS operating system and a trusted operating system executed on a chipset of said electronic device,

wherein the message becomes accessible to the targeted operating system, and

wherein the means for determining are set in operation in response to receipt of the message by the transmitter-receiver.

2. The electronic module according to claim 1, further comprising:

initialisation means to initialise a communication channel between said electronic module and said targeted operating system; and

means for sending to said targeted operating system, via said communication channel, notification of receipt of the message.

3. The electronic module according to claim 1, wherein the trusted operating system and the Rich-OS operating system are unable to send a command or a message to the electronic module.

4. The electronic module according to claim 1, wherein the means for determining set in operation without any operating system inter-positioned between the means for determining and the electronics module.

5. The electronic module according to claim 1, wherein the message comprises a frame, and

wherein the means for determining comprises means for reading a recipient field of said frame or said message to identify the targeted operating system.

6. The electronic module according to claim 5, wherein the means determining further comprises:

means for obtaining the address of a communications means of the execution environment of the targeted operating system, from a destination address included in the recipient field of said frame or of said message, the destination address being read by the means for reading.

7. The electronic module according to claim 1, wherein the means for determining comprises means for interpreting a command contained in the message.

8. The electronic module according to claim 1, further comprising:

means for making said message available in a memory accessible to the targeted operating system.

9. A transmitter-Receiver comprising an electronic module according to claim 1.

10. A terminal comprising:

a chipset, on which a Rich-OS operating system and a trusted operating system are executed, and

a transmitter/receiver,

wherein the terminal comprises an electronic module according to claim 1.

11. The terminal according to claim 10, wherein the electronic module is integrated in the chipset.

12. The terminal according to claim 10, further comprising:

a communication channel between said trusted operating system and said transmitter-receiver, so that the trusted operating system generates a secure message transmitted directly to the transmitter-receiver.

13. The terminal according to claim 10, wherein the terminal is a mobile telephony terminal.

14. A message routing method implemented by an electronic module, the method comprising:

determining an operating system targeted by a message received by a transmitter-receiver of an electronic device, from among at least a Rich-OS operating system and a trusted operating system executed on a chipset of said electronic device,

wherein the message becomes accessible to said targeted operating system, and

wherein the determining operates in response to receipt of the message by the transmitter-receiver.

15. (canceled)

16. A non-transitory computer-readable medium comprising instructions that, when executed by a processor, perform a method comprising:

determining an operating system targeted by a message received by a transmitter-receiver of an electronic device, from among at least a Rich-OS operating system and a trusted operating system executed on a chipset of the electronic device,

wherein the message becomes accessible to said targeted operating system, and

wherein the determining operates in response to receipt of the message by the transmitter-receiver.
