The method, designed to make the same information (K) available to several receivers (1) belonging to a group (G) of receivers, each receiver storing information (SA) spe cific to it, is characterized in that it includes the following steps: define a relation Ki-f(K, b, SA) where (f) is a given function, (K) is information common to all the receivers, and (b) is information different for each receiver and for each value of the information (K); —enable each receiver to access information (b) before making (K) available; and transmit the information (K) to all receivers, just before making (K) available; so that each receiver can calculate information (K) using said relation. |
