MANAGEMENT OF ACCESS TO A PLURALITY OF SECURITY MODULES INCORPORATED INTO A DATA-PROCESSING DEVICE

摘要

The invention relates to a method for managing the use, in a terminal, of a plurality of security modules (SIM1, SIM2) managed by an entity (STK) capable of requiring the provision of security codes in order to unlock the modules. The method is characterised in that it comprises: a first phase of accessing the modules (PH1), including a step of receiving (ET13-1, ET13-2), by the entity, codes of the modules, a step of transmitting (ET14-1, ET14-2) the received codes to the security modules, followed by a step of storing (ET16), in a security module referred to as the main module, at least one code received by the entity relative to a module (SIM2) other than the main module; and a second subsequent access phase during which the unlocking of the main module is followed by a step of transmitting at least one code from the main module to at least one other security module (SIM2) corresponding to said at least one code.

1. A method for managing the use, in a terminal, of a plurality of security modules (SIM1, SIM2) managed by an entity (STK) capable of requesting the provision of security codes (PIN1, PIN2) in order to unlock the modules, respectively, characterized in that it comprises
a first phase of accessing the modules (PH1), comprising
a step (ET13-1, ET13-2) of reception of the codes of the modules by the entity;a step (ET14-1, ET14-2) of sending the received codes to the security modules, followed by a step (ET16) of saving in a security module, referred to as the main module, (ET16) of at least one code (PIN2) received by the entity and relating to a module (SIM2) other than the main module; a subsequent second access phase (PH2) during which unlocking (ET25) of the main module is followed by a step (ET26, ET27) of transmitting at least one code (PIN2) from the main module to at least one other security module (SIM2) corresponding to said at least one code.
