摘要： Various embodiments utilize hardware-enforced boundaries to provide various aspects of digital rights management or DRM in an open computing environment. Against the backdrop of these hardware-enforced boundaries, DRM provisioning techniques are employed to provision such things as keys and DRM software code in a secure and robust way. Further, at least some embodiments utilize secure time provisioning techniques to provision time to the computing environment, as well as techniques that provide for robustly secure storage.

摘要： A DRM technique involves packaging an advertisement using a data structure that encapsulates a number of advertising segments along with signed information, such as a table of hashes, associated with some of the advertising segments. In one scenario, the data structure and the signed information are separately protected using public key and/or digital signature cryptographic schemes. The advertisement is delivered to a user of a consumer electronic device (CED) separately from delivery of a digital license, which governs user consumption of the advertisement. The digital license includes keys used in connection with the cryptographic scheme, and references a condition to be satisfied with respect to consumption of the advertisement. As advertising segments are verified and consumed by the user/CED, information is recorded and used to determine whether the license condition was satisfied. Satisfaction of the license condition may result in access to program content or additional licenses.

摘要： Portable digital rights for multiple devices is described. In an embodiment, a digital rights management (DRM) system includes a first device with a removable component configured as a token that is associated with a DRM license. The first device also includes a removable memory card that stores protected media content on which the first device can perform actions as permitted by the DRM license. The DRM system also includes a second device that can have the removable component and the removable memory card when removed from the first device and installed in the second device such that the second device can perform the actions on the protected media content as permitted by the DRM license.

摘要： Systems, methods, and/or techniques (“tools”) for binding content licenses to portable storage devices are described. In connection with binding the content licenses to the portable storage devices (“stores”), a host may perform authentication protocols that include generating a nonce, sending the nonce to a store, and receiving a session key from the store, with the session key being generated using the nonce. The store may perform authentication protocols that include receiving the nonce from the host, generating a random session key based on the nonce, and sending the session key to the host.
