    摘要： The invention relates to a method for protection of a file containing a number of descriptions of rights Di (i=l ... N), each right Di defining the use by a terminal of at least one resource and/or a digital content from a number of resources and/or digital content RCj (j=l ... M), each description of a given right Di comprising in particular, an identifier of said right Di, an identifier for each resource and/or content RCj the use of which is defined by the right Di, and the conditions of use of the resources and/or said content by the terminal. The method comprises the following steps: on receipt of the file of descriptions of rights Di by a terminal, memorizing said descriptions in the terminal and generating, for each resource and/or content RCj, a data structure (Id_ RCj, Id_Di) comprising the identifier of said resource and/or said content and the identifier of each right Di defining a use of said resource and/or said content RCj, and transferring each generated structure (Id_RCj, Id_Di) to a secure memory zone.

    摘要翻译： 本发明涉及一种保护包含多个权利描述Di（i = 1 ... N）的文件的方法，每个权利要求D定义终端在多个资源中的至少一个资源和/或数字内容的使用 和/或数字内容RCj（j = 1 ... M），给定权利的每个描述Di特别包括所述权利的标识符Di，每个资源的标识符和/或内容RCj，其使用被定义 通过所述右侧，终端使用所述资源和/或所述内容的条件。 该方法包括以下步骤：在终端接收权限描述文件Di时，在终端中存储所述描述，并且对于每个资源和/或内容RCj，生成包括标识符的数据结构（Id_RCj，Id_Di） 的所述资源和/或所述内容以及每个权限的标识符定义所述内容RCj的使用，将生成的每个（Id_RCj，Id_Di）结构传送到安全存储区域中。

    摘要： The invention relates to a method in which: a network head-end associates (112) with each segment of a list of at least one segment of a first segment block, a time datum that makes it possible to determine whether a deadline for sending an access rights request to an access rights server has changed; the network head-end sends (118) to the terminal, together with each segment in the list, the associated time datum thereof; the terminal receives (124), together with each segment in the list, the associated time datum thereof, then changes (144) a renewal deadline predetermined according to the last time datum received to obtain a new predetermined renewal deadline that enables the terminal to decide, according to the value thereof and at a given time before or equal to the changed deadline, to send an access rights request to the access rights server.
