摘要： A portable secure data file includes an encrypted data portion and a metadata portion. When a request associated with a current user of a device to access a portable secure data file is received, one or more records in the metadata portion are accessed to determine whether the current user is permitted to access the file data in the encrypted data portion. If a record indicates the user is permitted to access the file data, a content encryption key in that record is used to decrypt the encrypted data portion.
摘要翻译：便携式安全数据文件包括加密数据部分和元数据部分。当接收到与用于访问便携式安全数据文件的设备的当前用户相关联的请求时，访问元数据部分中的一个或多个记录以确定当前用户是否被允许访问加密数据部分中的文件数据。如果记录指示用户被允许访问文件数据，则使用该记录中的内容加密密钥对加密的数据部分进行解密。

摘要： Computer systems and environments implemented herein permit a local machine increased participation in authorizing access to protected content. An operating system attests to a computing environment at a corresponding computer system. If the computing environment is one permitted to access protected content, the operating system is permitted to regulate further (e.g., application) access to protected content in accordance with a procreation policy. As such, authorization decisions are partially distributed, easing the resource burden on a content protection server. Accordingly, this computing environment can facilitate more robust and efficient authorization decisions when access to protected content is requested.

摘要： The present invention extends to methods, systems, and computer program products for licensing protected content to application sets. Embodiments of the invention permit a local machine to increase its participation in authorizing access to protected content. For example, an operating system within an appropriate computing environment is permitted to determine if an application is authorized to access protected content. Thus, the application is relieved from having to store a publishing license. Further, authorization decisions are partially distributed, easing the resource burden on a protection server. Accordingly, embodiments of the invention can facilitate more robust and efficient authorization decisions when access to protected content is requested.

摘要： A virtual PCR (VPCR) construct is provided that can be cryptographically tagged as optionally resettable or as enduring for the life of a client (process, virtual machine, and the like) and that can be loaded into a resettable hardware PCR to make use of the functionality of a Trusted Platform Module (TPM). The VPCRs may cryptographically reflect their characteristics (resettable or not) in their stored values. Also, since the PCRs are virtualized, they are (effectively) unlimited in number and may be given general names (UUIDs) that are less likely to collide. The VPCRs can be loaded into a physical PCR as needed, but in a way that stops one piece of software from impersonating another piece of software. The VPCRs thus enable all software using the TPM to be given access to TPM functionality (sealing, quoting, etc.) without security concerns.
摘要翻译：提供虚拟PCR（VPCR）构造，其可以被加密地标记为可选择地重置或在客户端（过程，虚拟机等）的寿命中持久，并且可以将其加载到可重置的硬件PCR中以利用可信平台模块（TPM）的功能。 VPCR可以加密地反映其存储值的特性（可重置或不可复位）。此外，由于PCR被虚拟化，它们（有效地）数量无限制，并且可以被给予不太可能发生冲突的通用名称（UUID）。 VPCR可以根据需要加载到物理PCR中，但可以阻止一块软件冒充另一块软件。因此，VPCR可以使所有使用TPM的软件都能够获得TPM功能（密封，引用等），而无需安全考虑。
