A secure element includes a boot program comprises instructions for the execution a startup step to determine if a non-volatile memory stores an active operating system, and, in the affirmative, to launch execution of the operating system, an authentication step of a updater device, as a function of first authentication data determined by a secure element and second authentication data received from the updater device, and, in response to the authentication step, a storage step of a new operating system received from the update, device in the non-volatile memory and an activation step of the new operating system, when said instructions are executed by a microprocessor.

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.
