Targeted muting for communication between electronic appliances

摘要

A method for controlling the flow of data in a near field communication appliance having an interposed element and a plurality of secure elements connected to the interposed element is disclosed. The method includes receiving a first communication at a first one of the secure elements. The first communication is sent by an external appliance and suited to an application located in one of the secure elements. The method further includes testing, by means of the first secure element, whether the first secure element contains the application. The first secure element is muted if the first secure element does not contain the application. A corresponding near field communication appliance and terminals are also disclosed.

1. A method for controlling the 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, the method comprising:
receiving a first communication at a first one of the secure elements within the NFC appliance, the first communication sent by an external appliance and suited to an application located in one of the secure elements; testing, by means of the first secure element, whether the first secure element contains the application; and muting the first secure element in response to the first secure element not containing the application to prevent the first secure element from sending a not acknowledged message to the external appliance, wherein the interposed element is a communication bridge or hub between the external appliance and the secure elements included in the NFC appliance, and wherein the interposed element is separate from the secure elements and physically connected to the secure elements over an interface.
