    摘要： The invention relates to a method of securing an integer number n greater than or equal to 1 of messages MUi (i = 1 to n) transmitted by a sender terminal to a receiver terminal in which, prior to the sending, by the sender terminal, a‑ generating an ordered sequence comprising N data blocks Bj (j = 1 to N), N being an integer greater than or equal to n, b‑ for each message MUi (i = 1 to n), calculating a position pi in said ordered sequence of N blocks by means of a function F, c‑ encapsulating each message MUi (i = 1 to n) in the block Bj situated in position pi, and, d‑ transmitting the ordered sequence comprising the messages MUi to said receiver terminal, and on reception, by the receiver terminal, e‑ recalculating the positions pi (i = 1 to n) of the blocks Bj encapsulating the messages MUi by means of said function F, f‑ extracting the blocks Bj occupying the positions pi (i = 1 to n) of the ordered sequence received, g‑ extracting the messages MUi encapsulated in said blocks Bj.

    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.

    摘要： The invention relates to a method for providing protected multimedia content, during which a terminal: a) acquires (1408) a service date from a date server; and b) assesses (1414) a license time criterion corresponding to the last acquired service date. In said method: a head end associates (1202) the transmission date of the multimedia content with each segment thereof and transmits (1206) said date into a stream, together with the segment; then the terminal extracts (1400, 1402) the transmission date of the segment from the stream then compares the extracted transmission date with the last acquired date of service, and only if the extracted transmission date comes after said last acquired service date, the terminal acquires (1406) same as the service date and uses (1414) same as the last acquired service date when carrying out Step b), between two consecutive instances of carrying out Step a).

    摘要翻译： 一种用于提供受保护的多媒体内容的方法，其中终端a）从日期服务器获取服务日期，以及b）评估关于最后获取的服务日期的许可证的时间标准。 头端与多媒体内容的每个段，其发送日期相关联，并且与段一起以流形式发送它。 终端从流中提取节段传输日期，然后将提取的发送日期与最后获取的服务日期进行比较。 而且，只有提取的发送日期晚于最后获取的服务日期，才将其作为服务日期获取，并且在步骤a）的两个连续执行之间执行步骤b）时将其用作最后获取的服务日期。

    摘要： Method for broadcasting protected multimedia contents, in which; at predetermined intervals, an access rights server broadcasts (114) each new right of access to the broadcast multimedia contents only to those terminals for which the login is included in a broadcast list, in response to a predetermined event, a terminal sends (118) to the access rights server, via a point-to-point connection, a status message indicating to the access rights server that said terminal is in the ready state and, alternately, not sending said status message if said terminal is in the occupied state, and - in the absence of reception of the status message expected in response to the predetermined event, the rights server automatically removes (166, 168, 170, 172) the identifier of said terminal from the broadcast list.
