Abstract
The invention concerns a terminal (T) comprising an agent (AS) for processing a secure content encrypted with a key (KCN) and transmitted by a first server (SCN). In order to manage a secure access to the secure content, an application (AG) of a portable communicating object, such as a chip card, associated with a terminal stores one type of related digital right (TDN) and a certificate and transmitted by the agent and stores an access right (DA) and the key (KCN) related to the secure content transmitted from a second server (SAD). The application adapts the access right and the key and modifies the secure content, based on the type of right, and produces a secure access file based on the adapted access right and the key and on the certificate, the produced file being accessible by the terminal so that the agent may process the modified content.
