摘要： A method of verification of rights is disclosed, contained in a security module associated to an apparatus processing broadcasted digital data. The apparatus is connected to a management center transmitting encrypted rights messages for accessing the digital data. The method includes reception and reading by the security module of all or part of a rights message including at least one right and means for verifying the right, decryption and verification of the rights message and updating of a rights memory, and storage of all or part of the rights message in a messages memory. During a further verification step, the method includes identification of at least one right present in the rights memory, search of the corresponding stored rights message and verification of the rights message, comparison of the right contained in the rights message with the corresponding right stored in the rights memory, and determination of a default state when the result of the comparison indicates a difference.

摘要： The present invention proposes a solution to prevent a program flow in a processing unit from being modified with respect to an intended program flow, thereby ensuring that important steps such as verifying or authenticating are not bypassed. The invention is particularly aimed at security modules within receiver/decoders in a pay-TV system and involves performing a set of predetermined operations during the processing of entitlement management messages and/or entitlement control messages, said operations being redundant with respect to the normal processing of said messages while leading to the calculation of keys which can then be used to verify that the intended program flow has been respected.
摘要翻译：本发明提出了一种防止处理单元中的程序流在相对于预期程序流程被修改的解决方案，从而确保不绕过诸如验证或认证的重要步骤。本发明特别针对付费电视系统中的接收机/解码器内的安全模块，并且涉及在处理授权管理消息和/或授权控制消息期间执行一组预定操作，所述操作相对于正常处理是冗余的的所述消息，同时导致密钥的计算，然后可以使用该密钥来验证预期的程序流已被遵守。
