A method implemented in an integrated-circuit module including a processor accessing a non-volatile memory wherein execution-context-defining software applications to be executed by the processor for communication with a device are stored, and to access a volatile memory storing execution data of a software application currently being executed. The software applications include a first being executed and a second previously suspended, the method including, upon receiving a command from the electronic device: suspending execution of the first software application being executed including saving the content of the volatile memory in a first backup location of the non-volatile memory, stopping the execution of the first software application; and resuming the previously suspended execution of the second software application including transferring into the volatile memory, from a second backup location of the non-volatile memory, execution data relating to the previously suspended execution of the second software, and executing the second software application.

A card () generates a dynamic security code for a card transaction, e.g. a card not present (CNP) transaction. The card () receives a request () to generate a dynamic security code from an electronic device () external to the card via an external card interface (). The card () receives a message () comprising a time via the external card interface (). The card () computes () the dynamic security code based on the time and a key (dCVV-key) stored at the card. The card () sends the dynamic security code () to the electronic device () via the external card interface () for display on a display () of the electronic device (). The card () may determine () an authenticity of the message comprising the time.

Dynamic security code for a card transaction

Disclosed is management of a plurality of active subscriber profiles at the same time within the same secure element integrated in a host terminal. A baseband processor of the terminal and a communication interface controller of the secure element together establish different separate links for each one of the active profiles. It is thus possible to address, and therefore to simultaneously use, a plurality of profiles. A link can be the conventional ISO 7816 link. The HCI/SWP interface allows a large number of logical links (or HCI pipes) to be established using a single additional tab for connecting the secure element in the terminal. Each active profile is thus associated with an HCI pipe for routing messages relating thereto. As a variant or in combination, an SPI interface allows master-slave logical links to be established.

Disclosed is a method for administering a communication channel between two host components of a mobile NFC device. The method includes a step of updating the whitelist of a first host component, then a step of notifying the update to a second authorised host component. The notifying step informs the second host component of the status of the whitelist of the first host component in order to prevent the transmission of requests to create a communication channel which would then be rejected. Also disclosed is a mobile NFC device.

Method and secure device for performing a transaction

The invention relates to methods and devices for updating a cache memory in a telecommunications terminal suitable for co-operating with a subscriber identity module. Some implementations of the subscriber identity module may perform operations that include detecting a modification of an elementary file and generating update data associated with the modified elementary file. During a starting stage, the operations may further include receiving a start message from the terminal; receiving a request serving to identity an elementary file for processing; sending the update data associated with the elementary file for processing; and reading the elementary file in compliance with a read command from the terminal. The invention also provides corresponding methods and devices for the terminal, and the corresponding module and terminal.

Methods for updating a cache memory of a telecommunications terminal

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.
