Access rights lists, such as capacity or access control lists, are
dynamically managed in a data processing element such as a smart card
from an administrator server. To access an access rights list from the
server, the list is signed in the server so that a signature can be
transmitted to the card. The card compares the signature received from
the server to signatures determined according to the access rights lists
contained in the card and keys associated with those lists. Server access
to an identified list is only authorized when it corresponds to a
signature which is found among the determined signatures in the card and
which is identical to the received signature.
