摘要： In accordance with one or more aspects of the separating keys and policy for consuming content, content has a corresponding leaf license, and the leaf license has one or more associated root policy addenda. Each root policy addenda includes policy identifying when it is permissible to decrypt and consume the content, but excludes a content key to decrypt the content. The content can be decrypted and consumed only if the policy identifies that it is permissible to decrypt and consume the content.
摘要翻译：根据用于消费内容的分离密钥和策略的一个或多个方面，内容具有相应的叶子许可证，并且叶子许可证具有一个或多个相关联的根策略附录。每个根策略附录包括确定何时允许解密和使用内容的策略，但不包括内容密钥来解密内容。只有当策略确定允许解密和使用内容时，内容才能被解密和消耗。

摘要： In accordance with one or more aspects, a license for content is retrieved, the license having been previously embedded in the content. A requested action is allowed to be performed with the content only if a standalone license, or both a leaf license and a root license, indicate that the action with the content is permissible. Leaf licenses and/or standalone licenses can be embedded by a source of the content and/or by a target device that receives the content. Additionally, licenses can include one or more rules indicating where a target device that receives the content is to store the licenses.
摘要翻译：根据一个或多个方面，检索内容许可证，该许可证先前已经嵌入在内容中。仅当独立许可证，叶子许可证和根许可证都指示允许使用内容的操作时，才允许与内容一起执行请求的操作。叶片许可证和/或独立许可证可以由内容源和/或由接收内容的目标设备嵌入。此外，许可证可以包括一个或多个规则，指示接收内容的目标设备在哪里存储许可证。

US20100131765A1 ANONYMOUS VERIFIABLE PUBLIC KEY CERTIFICATES 有权
标题翻译：匿名可验证公开的关键证书

摘要： The anonymity of a user at a client computer may be preserved when authenticating with an on-line service or content provider through the use of an anonymous and verifiable (i.e., “blind”) certificate set that is created by a certificate authority from a fixed-size set of PKI key pairs. The certificate authority randomly selects a subset of PKI key pairs to generate the blind certificate set where each certificate in the set includes a respective public key from the PKI key pair subset. The certificate authority also sends the private keys from the PKI key pair subset to the user. During authentication, the client computer is configured to randomly select a subset of one or more certificates from the set to present to the provider. The provider will encrypt content using the public keys in the subset of certificates and the client will decrypt the content with the corresponding private keys.
摘要翻译：通过使用由证书颁发机构创建的匿名和可验证（即，“盲”）证书集从固定的在线服务或内容提供商进行认证时，可以保留客户端计算机上的用户的匿名性一套PKI密钥对。证书颁发机构随机选择PKI密钥对的子集以生成盲证书集，其中集合中的每个证书包含来自PKI密钥对子集的相应公钥。证书颁发机构还将私钥从PKI密钥对子集发送给用户。在认证期间，客户端计算机被配置为从集合中随机选择一个或多个证书的子集以呈现给提供者。提供商将使用证书子集中的公钥加密内容，客户端将使用相应的私钥对内容进行解密。

摘要： A protocol is provided that permits a third-party key issuing entity to have its issued keys protected by an unrelated key protecting entity. In at least some embodiments, a trusted key protecting entity is injected, in a sense, in a conversation between the third-party key issuing entity and a client to which one or more keys are distributed. The trusted key protecting entity is able to apply various protections which, in at least some embodiments are unknown to the key issuing entity, to a distributed key which can then be used by the client to access protected content.
摘要翻译：提供了允许第三方密钥发布实体将其发布的密钥保护为不相关的密钥保护实体的协议。在至少一些实施例中，信任密钥保护实体在某种意义上被注入在第三方密钥发布实体与分发了一个或多个密钥的客户端之间的会话中。可信密钥保护实体能够应用各种保护，这些保护在至少一些实施例中是密钥发布实体未知的分配密钥，然后客户端可以使用分配密钥来访问受保护的内容。
