Abstract: Techniques for a trusted system for secure content distribution and trusted recording of content consumption are described. In some embodiments, the trusted system transcodes and transcrypts a media content item using a key obtained from a content provider and one or more keys based on an entitlement from a service provider to generate an encrypted media content item. The trusted system further receives a request to provide the media content item to a client device. The trusted system also obtains a signed audit token recording the request upon an authorization by the service provider based on the entitlement and a confirmation by the content provider, where the signed audit token is signed by the content provider and the service provider. The trusted system additionally provides the one or more keys for decrypting the encrypted media content item and reports the signed audit token.

Abstract: A lockable nut system for use with threaded steel bar which includes a screw threaded nut for engagement with the threaded steel bar and a locking member which is slidably engageable with the bar. The locking member is adapted to resist rotation about the bar and is also axially engageable with the nut to prevent rotation of the nut. The locking member has one or more fingers to engage the nut with an end of the finger being displaced to engage the nut as a result of deformation of a finger actuating tab or a dished body of the locking member. The locking member may engage the bar by displacement of an end of at least one tongue as a result of deformation of a tongue actuating tab during compression between the nut and a second structure.
