Abstract
An electronic device, for example for near field communication (NFC), includes a device host including an operating system (OS), a trusted execution environment (TEE), and a near field communication (NFC) controller configured to enable communication of the electronic device with other devices. The NFC controller is coupled to the device host by a data channel for data exchange and a control channel for control information exchange, and the control channel is provided between the TEE and the NFC controller.
Claims13
An electronic device comprising:
- a device host comprising an operating system (OS) and a trusted execution environment (TEE);
- and
- a near field communication (NFC) controller configured to enable communication of the electronic device with other devices, the NFC controller being coupled to the device host by a data channel to exchange data and a control channel to control information exchange,
- wherein the control channel is coupled to the TEE and the NFC controller rather than to the OS.
A communication method for an electronic device including a device host including an operating system (OS), a trusted execution environment (TEE), and a near field communication (NFC) controller configured to enable communication of the electronic device with other devices, the method comprising:
- establishing a data channel between the NFC controller and the device host to enable data exchange between the NFC controller and the device host;
- and
- establishing a control channel between the NFC controller and the device host to control information exchange,
- wherein the control channel is coupled to the TEE and the NFC controller rather than to the OS.
A non-transitory computer-readable recording medium that stores therein a computer program product which, when executed by a processor, causes the processor to perform a method for an electronic device comprising a device host including an operating system (OS), a trusted execution environment (TEE), and a near field communication (NFC) controller configured to enable communication of the electronic device with other devices, the method comprising:
- establishing a data channel between the NFC controller and the device host to enable data exchange between the NFC controller and the device host;
- and
- establishing a control channel between the NFC controller and the device host to control information exchange,
- wherein the control channel is coupled to the TEE and the NFC controller rather than to the OS.
An electronic host device comprising:
- a device host comprising an operating system (OS) and a trusted execution environment (TEE);
- a first interface configured to exchange data over a data channel provided between the host device and a near field communication (NFC) controller configured to enable communication of the electronic device with other devices;
- and
- a second interface configured to exchange control information over a control channel between the TEE and the NFC controller,
- wherein the control channel is coupled to the TEE and the NFC controller rather than to the OS.
