PROCESSING OF DATA RELATING TO A DATA NETWORK

摘要

According to the invention and in order to process, e.g. cipher or decipher, digital data (DAT) created, stored, used or to intended to be used by an application (AP) dedicated to a data network (RD) and executed in a terminal, with a memory access request (RA) including the digital data (DAT) being emitted by the application to a terminal exploitation system, a protection system (SP) intercepts the memory access request (RA) to the exploitation system. The latter identifies the application (AP) at the origin of said request, a parameter server (SVP) determines an identifier (IRD) of the data network associated with the application (AP), and a key generator (GC) generates a key (KPD) according to the data network identified by said identifier (IRD) in order to process the digital data according to the generated key (KPD).
