Abstract
The invention provides a method for reducing occupancy of descriptors used for protecting files in storage. The method includes separating the functions files are going to be subjected to from the protection modes to which said functions subscribe. The descriptors comprise a number of octets equal to the number of protection modes proposed. The bits of these octets, depending on whether they are active or inactive, refer to function memory words whose number is directly equal to the number of active bits in the mode memory words. The function memory words comprise references to secret codes to be used for implementing the desired security functions.
