摘要： A key generation system is disclosed that provides for the generation of privileged group keys based on the input of a privileged group. The system performing the key generation has stored component keys corresponding to every possible subset X of the unitary set, where subsets X have k or fewer members. The privileged group key is generated for the privileged set by passing ordered component keys of subsets X that do not contain members of the privileged set to a pseudo random function.

摘要： The invention relates to a method for updating a security processor and to a corresponding system, computer program and security processor. Said method for updating a security processor (16) for a decoder (14) includes a step of downloading at least one code module from a headend (6), including the sub-steps of: encrypting (32) the module by means of an encryption key and algorithm that are specific to said module; cutting (34) the module into a plurality of blocks having a size that is specific to said module; integrating (34) each one of the blocks of the module in a specific message; broadcasting (36) each one of said messages; receiving (38) said messages in the decoder (14); extracting (42) blocks of the module from said messages; decrypting (42) blocks of the module; and storing (44) blocks of the module in a memory space dedicated to said module.

摘要： A mobile terminal and controlling method thereof are disclosed, which facilitates a terminal to be used in further consideration of user's convenience. The present invention includes displaying a channel list in which receivable channels including at least one pay broadcast channel are listed, receiving a broadcast viewing authority for watching the pay broadcast channel from a broadcast viewing authority server via a broadcasting network or an internet network, storing the received broadcast viewing authority, and updating the stored broadcast viewing authority each time a broadcast mode is entered. Accordingly, when the broadcast viewing authority is updated in the mobile terminal to prevent illegal copying or piracy of the broadcast viewing authority, the terminal user needs not to temporarily stop viewing the corresponding broadcast. Moreover, each time the mobile terminal enters a broadcast mode, an old broadcast viewing authority is deactivated and a new broadcast viewing authority is received. Therefore, the illegal copying or piracy of the broadcast viewing authority stored in the mobile terminal can be basically prevented.
摘要翻译：公开了一种移动终端及其控制方法，便于终端进一步考虑用户的便利性。本发明包括显示频道列表，其中列出了包括至少一个付费广播频道的可接收频道，经由广播网络或互联网从广播观看授权服务器接收观看付费广播频道的广播观看权限，接收广播观看权限，并且每次输入广播模式时更新存储的广播观看权限。因此，当在移动终端中更新广播观看权限以防止广播观看权限的非法复制或盗版时，终端用户不需要暂时停止观看相应的广播。此外，每当移动终端进入广播模式时，旧的广播观看权限被停用，并且接收到新的广播观看权限。因此，可以基本上防止存储在移动终端中的广播观看授权的非法复制或盗版。
