Abstract (en)
[origin: FR2898001A1] The method involves accessing a certificate relative to a security officer (AS) and a digital right type exploited by the officer, and storing a encrypting key (KCN) and a access right relative to the content, where the key and the right are transmitted from a digital right administration server simultaneously. The key and the right are adapted, and the content is modified based on the type. A secured access file is produced based on the adapted right, key and certificate, where the file is accessible by a mobile terminal so that the officer processes the modified content based on the file. Independent claims are also included for the following: (1) a system for managing secured access to a secured digital content encrypted with a key in a portable communicating object associated to a terminal (2) a portable communicating object for managing secured access to a secured digital content (3) a computer program is adapted to be implemented in a portable communicating object for managing secured access to a secured digital content.
