Abstract

The program is constituted by personalized program elements containing an identification of the recipient or addressee, the access to each program element being reserved for a single recipient and is conditioned for the possession of an access title covering the access criteria to the service and the poss-ession of an individual identification on the part of each recipient. The access title control message enables users of the service to calculate, on the basis of the single cryptogram of a root control word and the identification of the recipient, all the personalized control words which will enable each recip-ient and him alone to descramble the elements relating to him.
