摘要:
A digital rights management (DRM) system operates on a computing device and requires a black box for performing decryption and encryption functions. To obtain the black box from a black box server, the DRM system requests such black box from such black box server. The black box server in response generates the black box, where such black box is unique and has a public/private key pair. The black box server then delivers the generated black box to the DRM system and the DRM system installs the delivered black box in such DRM system.

Methods and apparatus for a secure sleep state are disclosed. An example method includes, in response to an initiation of a sleep state of a computing platform, encrypting a memory of the computing platform; and decrypting the memory when resuming the computing platform from the sleep state, wherein placing the computing platform in the sleep state includes powering down a portion of the computing platform and preserving a state of the computing platform.

A digital rights management (DRM) system, an application, and a DRM digital license for the application are all on a computing device. The application is for being executed to perform a function and includes code requiring that the DRM system determine that the application is allowed to be executed to perform the function based on the license. The application further includes code for determining that the application is to be executed on one of the computing device or in connection with the DRM system.

In order to allow for security beyond revocation lists, a policy regarding when permissions may be granted (in the form of a rights document, e.g. a use license or a certificate) is enforced. When a request is made for a rights document, the requester submits an account certificate which includes certain metadata regarding the requester. This metadata is analyzed to determine whether it meets a specific policy before the request is granted. If the request is not granted, the cause of the rejection may be overcome, for example by updating or upgrading some system component (hardware or software) in the requesting system. In certain cases, such an update to overcome a policy-based rejection may be performed transparently to the user.

An enforcement architecture and method for implementing digital rights management are disclosed. Digital content is distributed from a content server to a computing device of a user and received, and an attempt is made to render the digital content by way of a rendering application. The rendering application invokes a Digital Rights Management (DRM) system, and such DRM system determines whether a right to render the digital content in the manner sought exists based on any digital license stored in the computing device and corresponding to the digital content. If the right does not exist, a digital license that provides such right and that corresponds to the digital content is requested from a license server, and the license server issues the digital license to the DRM system. The computing device receives the issued digital license and stores the received digital license thereon.
