<p>The invention relates to a method whereby access rights lists (ACL), such as capacity or access control lists, are dynamically managed in a data processing element such as a chip card (CA) from an administrator server (SAD). In order to access an access rights list (ACL) from the server, the list is signed (ET4) in the server so that a signature (SGAD) can be transmitted (ET5) to the card. The card compares (ET6) the signature received to signatures determined according to the access rights lists contained in the card and keys associated with said lists respectively. Server access to a found list (ACL) is only authorised when it corresponds to a signature which is found among the determined signatures in the card and which is identical to the signature received.</p> |
