Abstract
The invention concerns a method for processing confidential codes in a system with security functions (180) consisting in receiving a code; verifying a first clearance, conditioned by a fist code, to access a first function (180); authorising access to the first function (180) if the first clearance is identified; and if the first clearance is not identified, using the code to verify a second clearance, conditioned by a second code distinct from the first code, to activate at least a second function (170), without revealing the fact that the code does not enable to obtain the first clearance. The invention also concerns a device for implementing the method.
