An electronic appliance includes a first processor and a secure electronic entity equipped with a second processor, the electronic appliance being designed to operate by the execution by the first processor of a trusted operating system. An element situated outside the secure electronic entity and distinct from the trusted operating system is designed to trigger the execution of an application by the second processor; the application executed by the second processor is designed to request the implementation of a service of the trusted operating system. A method implemented in such an electronic appliance is also described.

Disclosed are methods performed by, and devices including, a microcircuit card that makes it possible to set up a communication session between the microcircuit card and a contactless communication module via an SWP interface. An implementation of the method comprises: an initialization phase for the SWP interface; and a negotiation phase between the microcircuit card and the contactless communication module, the contactless communication module being suitable for maintaining the power supply of said microcircuit card during these phases. Among other reasons, the method is remarkable in that the microcircuit card prolongs said negotiation phase until the end of a procedure internal to the microcircuit card.

An embodiment of an emergency call system comprises a device for triggering an emergency call and a communications device having a secure element. In various implementations, the secure element includes at least two profiles, one of which is an emergency profile; means suitable for receiving, over a local communications channel, an event issued by the device for triggering an emergency call; means for activating an emergency profile, enabling emergency calls to be made in a communications network, if said profile is not already active; and means for calling an emergency number in said network in order to make said emergency call.


In an electronic device designed to function in a trusted execution environment (TEE), because of the execution of a trusted operating system by a processor of the electronic device, or in a rich execution environment (REE), a method of loading files into random access memory includes the following steps: An associated electronic device is also proposed.

An intermediary third-party receives, from a master device, a batch of pre-generated secure commands; plays it so as to send sequentially, to a slave device, the commands. The batch includes an initial command indicating the establishment of a channel secured with a session key dependent on a sequence counter, and second commands protected by a MAC code that is a function of the session key. An update of the sequence counter in non-volatile memory of the slave on each new establishment of a secure channel renders the pre-generated batch obsolete by virtue of a new session key. In order to allow the batch to be replayed, the invention provides for each update value of the counter to be temporarily stored in volatile memory, and for the current value to be overwritten in non-volatile memory on predefined events, including a test counter reaching a maximum number of replays.
