AbstractThe invention relates to a process for loading a protected storage zone of an information processing device, with confidential data and/or programs, and to the associated information processing device.The information processing device (1) includes a module (8) that includes a non-volatile memory having a protected zone (11) which is read-write accessible to a processing means (9) inside the module, but is at least write-protected from outside the module. The process executes a transfer of confidential information to the protected zone (11) from an analogous protected zone (27) of a portable object (21) with a structure similar to that of the module. The portable object is received in a portable object reader (6) which is provided in the information processing device.
