摘要： A process may be utilized by a DVR. The process characterizes a set of content as a plurality of segments as the set of content is received. Each of the segments has a segment length according to a predetermined time interval. Further, the process encrypts each of the segments with a corresponding content encryption key to generate a plurality of encrypted segments. The corresponding content encryption key for each of the segments is generated by the DRM component. In addition, the process stores each of the encrypted segments for playback with trick play features in accordance with an expiration content rule having a time limit on the temporary playability of the set of content.

摘要： The present invention discloses an apparatus and method for transferring digital content data. In one example, original digital content data stored on a first device in an encrypted state is transcoded (after being decrypted) to create a modified version of the original digital content data. The modified version of the original digital content data is then encrypted with a new content key. The modified version and at least one content key generator are transferred to a second device, where the at least one content key generator is used to recreate the new content key for enabling (and decrypting) the modified version of the original digital content data at the second device. Notably, the original digital content data stored in the first device is disabled contemporaneously with the transfer of the modified version and the at least one content key generator to the second device. Afterwards, the disabled original digital content data is re-enabled on the first device, and disabled on the second device.

摘要： A process composes a content license for a set of content. The content license has a static portion and a dynamic portion. Further, the process inserts a master key into the static portion. In addition, the process inserts a plurality of content rule sets of values into the dynamic portion and composes a unique content encryption key for each segment of content associated with one of the content rule sets of values as each of the content rule sets of values is sequentially received during recording of the content. The unique content encryption key is based on the master key and at least a subset of the content rule set of values for a corresponding segment of the content. The unique content encryption key is utilized for encryption of each segment of the content to generate a plurality of encrypted content segments for storage on the storage medium.

摘要： A system for rating security levels a device according to the characteristics of functions executing within secure hardware components in the device. The security level of a host is placed in a digital certificate along with a corresponding private key at the time of manufacture of a device. The digital certificate can be provided to an inquiring device so that more comprehensive systme-wide security levels can be communicated and maintained. Where a network uses ticket-based key management protocols, the security rating, or level, is transferred from the certificate to an issued ticket. Inquiring devices can then check security levels of target devices by using certificates or tickets and perform transfers or grant authorizations accordingly. In a preferred embodiment a security ratings system uses six levels of security. The levels are structured to include characteristics about a device’s processing. That is, the levels provide information on the amount and type of sensitive processing that can occur in non-secure (or low security) circuitry or components within a device. This gives a bette indication of how prone a device is to threats that may be of particular concern in content delivery networks. Additional qualifiers can be optionally used to provide further information about a security level. For example, the degree of handling time management processing within secure hardware and whether a particular codec, watermarks of fingerprings are supported within secure hardware can each be represented by a policy qualifier.
摘要翻译：根据在设备中的安全硬件组件内执行的功能的特性来对设备进行安全级别评估的系统。在制造设备时，主机的安全级别与相应的私钥一起放置在数字证书中。数字证书可以提供给查询设备，以便可以传达和维护更全面的系统级的安全级别。如果网络使用基于票证的密钥管理协议，则安全评级或级别将从证书转移到颁发的机密。然后，查询设备可以通过使用证书或票证来检查目标设备的安全级别，并相应地执行转移或授权。在优选实施例中，安全评级系统使用六级安全性。这些级别的结构包括有关设备处理的特性。也就是说，这些级别提供关于可以在非安全（或低安全性）电路或设备内的组件中发生的敏感处理的数量和类型的信息。这给出了设备对内容传送网络中可能特别关注的威胁的倾向。可以选择使用其他限定词来提供有关安全级别的进一步信息。例如，安全硬件内的处理时间管理处理程度以及特定的编解码器，指纹的水印在安全硬件中是否被支持都可以由策略限定符表示。

摘要： A method of authentication and authorization over a communications system is provided. Disclosed herein are systems and methods for creating a cryptographic evidence, called authentication/ authorization evidence, AE, when a successful authentication/ authorization between a client and an authentication server is complete. There are a variety of methods for generating AE. For instance, the AE can be data that is exchanged during the authentication signaling or data that results from it. A distinctive point being that AE results from the authentication process and is used as prior state for the following TLS exchange. An example for creation of AE, is as follows: EAP authentications typically result in an Extended Master Session Key (EMSK). The EMSK can be used to create an Evidence Master Key (EMK) that can then be used to create AE for a variety of servers.
摘要翻译：提供了一种通信系统的认证和授权方法。本文公开了当客户端和认证服务器之间的成功认证/授权完成时，用于创建加密证据的系统和方法，称为认证/授权证据。有多种生成AE的方法。例如，AE可以是在认证信令期间交换的数据或由其产生的数据。一个独特之处在于，AE来自认证过程，并被用作以下TLS交换的先前状态。创建AE的示例如下：EAP认证通常导致扩展主会话密钥（EMSK）。 EMSK可用于创建证据主密钥（EMK），然后可用于为各种服务器创建AE。
