Abstract: A secure element may be coupled to a host and detects a reboot state of the host based on a state of a reset alert signal received from the host. The secure element further generates a reboot flag indicative of a reset operation of the host. Further, the secure element receives an access request from the host to access a plurality of secure functions of the secure element. Based on the access request, the secure element may determine an authorization state between the host and the secure element. The secure element regulates access of the host to the plurality of secure functions based on a status of the reboot flag and the authorization state.

Abstract: It is described a method, a control device, and a computer program for enabling/disabling at least one near field communication (NFC) function of a mobile device (MD). It is further described such a MD. The method comprises (a) associating the at least one NFC function to be enabled/disabled with a corresponding secure application (SA) installed in a secure element (SE) system; (b) checking whether the SA complies with a predefined secure condition; (c) if the SA complies with the predefined secure condition, transmitting a notification from the SA to the NFC control system (NFCC) via an interface between the SE system and the NFCC; and (d) enabling/disabling, by the NFCC, the at least one NFC function based on information comprised by the transmitted notification.

Abstract: In accordance with a first aspect of the present disclosure, a near field communication (NFC) device is provided, comprising: an NFC front-end circuit configured to perform a communication with an external device; at least one processing unit configured to process one or more transactions between the NFC device and the external device; an NFC controller configured to control the NFC front-end circuit; wherein the NFC controller is configured to block a current data frame, which is being received by the NFC front-end circuit, if the processing unit has not fully processed a previous data frame. In accordance with a second aspect of the present disclosure, a corresponding method of operating a near field communication (NFC) device is conceived. In accordance with a third aspect of the present disclosure, a corresponding computer program is provided.
