摘要： This invention relates to a system and a method of generating an Authorized Domain (AI)), the method comprising the steps of selecting a domain identifier (Domain ID) uniquely identifying the Authorized Domain, binding at least one user (P1, P2, ..., PN 1 ) to the domain identifier (Domain ID), and binding at least one device (Dl, D2, ..., DM) to at least one user (P1, P2, ..., PN1), thereby obtaining a number of devices (D1, D2, ..., DM) and a number of users (P1, P2, ..., PN1) that is authorized to access a content item (C1, C2, CN 2 ) of said Authorized Domain (100). Hereby, a number of verified devices (Dl, D2, ..., DM) and a number of verified persons (P1, P2, ..., PN1) that is authorized to access a content item of said Authorized Domain (100) is obtained. Additionally, it is possible to enable automatic assignment of imported content being imported on a device belonging to the Authorized Domain (AD) since it now is given to which person a given authorized device belongs to. Further, a simple and efficient way of implementing domain boundaries is enabled.

摘要： For conditional access purposes a stream is used in which at least two different decryption algorithms are needed for decryption of packets that encode different interspersed parts of the same signal for (quasi-)continuous rendering (such as an audio or video signal). Information is included in the stream to indicate dynamically which decryption algorithm should be used for which packets. In this way, it is possible for example to use a more robust algorithm with a less frequently changing key and a less robust algorithm with a more frequently changing key, interspersed with one another for the same signal. Also, different algorithms may be used for transcrypted and not transcrypted-packets of the same signal for example when an alternative is needed for the original encryption algorithm that was used for the non-transcrypted packets.
摘要翻译：对于条件访问目的，使用流，其中需要至少两个不同的解密算法来解密编码用于（准）连续渲染（例如音频或视频信号）的相同信号的不同散置部分的分组。信息被包括在流中以便动态地指示哪个分组应该使用哪个解密算法。以这种方式，例如，可以使用具有频率变化较小的键的更健壮的算法和具有更频繁变化的键的较不健壮的算法，对于相同的信号彼此散布。此外，不同的算法可以用于相同信号的加密而不是转发的分组，例如当用于非加密分组的原始加密算法需要替代方案时。

摘要： In whitelist-based authentication, a first device (102) in a system (100) authenticates itself to a second device (103) using a group certificate identifying a range of non-revoked device identifiers, said range encompassing the device identifier of the first device (102). Preferably the device identifiers correspond to leaf nodes in a hierarchically ordered tree, and the group certificate identifies a node (202-207) in the tree representing a subtree in which the leaf nodes correspond to said range. The group certificate can also identify a further node (308, 310, 312) in the subtree which represents a sub-subtree in which the leaf nodes correspond to revoked device identifiers. Alternatively, the device identifiers are selected from a sequentially ordered range, and the group certificate identifies a subrange of the sequentially ordered range, said subrange encompassing the whitelisted device identifiers.

摘要： A system (100) comprising a plurality of interconnected devices (101-105) and being arranged to provide the devices (101-105) conditional access to protected content items, characterized in that the system (100) is arranged to restrict the number of simultaneous sessions involving said protected content items to a predetermined total limit. Preferably the system (100) restricts the number of content items that can be accessed simultaneously to the predetermined limit. Security modules (300) such as smart cards can be used for this purpose. Each security module (300) may be arranged to restrict the number of content items to which it provides access simultaneously to an individual limit, which can change over time. The system restricts the sum of the individual limits to the predetermined total limit. If the limit is reached, further sessions may be refused or allowed at reduced quality level.

摘要： A method of validating an access operation to content on a device, comprising evaluating a license associated with the content, characterized by further evaluating a ruleset applicable to the content and validating the access operation only if the license and the ruleset both permit the access operation. The license may indicate the ruleset. Alternatively the ruleset applicable to the content may be determined by determining a characteristic of the content and selecting the ruleset based on the determined characteristic. The characteristic preferably is one of: a type of the content, a source of the content, a classification of the content. In an embodiment one or more links are evaluated which associate a person and/or the device to an authorized domain and a link associating the ruleset to the authorized domain is evaluated as well. Also a system configured for executing the method.

摘要： A method of and system for digital rights management, in which access to a piece of content is granted in accordance with a license owned by a license owner to a client who is a member of a domain. This requires successfully verifying that a membership relation exists between the client and the domain as reflected in a first state variable, and that an association relation exists between the license owner and the domain as reflected in a second state variable. Both relationships are revoked by executing an online protocol between the parties in the relationship after which both remove the corresponding state variable. The domain controller propagates the state administration relating to the domain is propagated to the client so that the client can update its state administration.
