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.

Abstract: An electronic device for near field communication (NFC) includes a processor including one or more applications and a controller controlling NFC communication between a reader/writer device and the processor. The controller includes a communication unit that exchanges communication between the external reader/writer device and the processor. A parser parses communication exchanged between the reader/writer device and the processor. The parser is configured to detect a predetermined setting of a response code within an authentication response sent by the processor in response to an authentication request received from the reader/writer device, the predetermined setting indicating that an application of the processing unit is in an authenticated state. A further controller controls the communication unit not to respond to an anti-collision request received from the reader/writer device and/or not to forward an anti-collision request to the processor if the anti-collision request is directed to an application in an authenticated state.
