Methods and appliances for forwarding communication between external appliances and secure elements using an interposed element and near field communication (NFC)

摘要

A method for controlling the flow of data in a near field communication appliance having a plurality of secure elements is provided. The method includes receiving a first communication, sent by an external appliance, which is intended for an application located in one of a plurality of secure elements of the near field communication appliance. The method further includes determining which of the secure elements contains the application, and taking measures in order to ensure that a further communication exclusively between the external appliance and the secure element contains the addressed application. In addition, appropriate mobile terminals for NFC communication are disclosed.

1. A method for controlling flow of data in a near field communication (NFC) appliance having an interposed element and a plurality of secure elements connected to the interposed element in a transparent manner, the method comprising:
receiving a first communication, sent by an external appliance, by the near field communication appliance; determining which of the secure elements contains an application suited to the first communication; forwarding the first communication by means of the interposed element to the secure element which contains the application; and temporarily changing the interposed element from a transparent connection mode, in which the interposed element converts the data from RF information to digital information and forwards the digital information in real time to the secure element which contains the application, to a buffered connection mode with at least one of the secure elements, in which the digital information is buffer-stored or buffered in the interposed element and not forwarded in real time to the secure element which contains the application.
