Abstract
A method for updating the firmware of a security module allowing it to “jump” towards a dedicated separate patch message stream thanks to a trigger messages stream broadcasted in a main stream of management messages. The trigger messages comprise version information allowing establishing whether the security module is up-to-date, and an identifier indicating to the security module the suitable patch stream. If the current version of the firmware of the security module is inferior to the patch version, the security module is directed towards the stream of patch messages designated by the identifier included in the trigger messages. Once the update of the firmware is complete, the security module is again directed towards the main stream. This return can be carried out automatically, namely with a switch message comprising an identifier of the first stream.
