摘要： A device renders content on a medium by obtaining a table from the medium, obtaining a device key (DK) of the device and an index value of such (DK), indexing into an entry of the table based on the obtained index value, selecting an encrypted secret from the indexed-into entry, applying the obtained device key (DK) to the selected encrypted secret to expose the secret, and applying the exposed secret to render the content.

摘要： A system and method for creating and conducting presentations on a surface may include an authoring mode, a preprocessing mode and a presentation mode. During an authoring mode, a user may create a surface presentation. In response to a command to play the created presentation, the system enters the preprocessing mode. During the preprocessing mode, a presentation is preprocessed and prepared for presentation. When preprocessing is complete, the presentation mode is entered. During the presentation mode, the infinite surface presentation is presented such that a user may navigate through the presentation.

摘要： To render content on a medium, a device obtains a table from the medium, obtains a private key of the device (PR-PD), indexes into an entry of the table based thereon, obtains (PU-PD(RND)) from the indexed-into entry of the table, and applies (PR-PD) to (PU-PD(RND)) to expose a random key (RND). Then, the device obtains (RND(PR-PM)) from the table, applies (RND) to (RND(PR-PM)) to expose a private key of the medium (PR-PM), obtains (PU-PM(KD)) from the license, applies (PR-PM) to (PU-PM(KD)) to expose a content key (KD), obtains (KD(content)) from the storage medium, applies (KD) to (KD(content)) to expose the content.

摘要： A computing device has a running real-time secure clock adjustable only according to trusted time as received from an external trusted time authority, a time offset within which is stored a time value adjustable by at least one of the user and the trusted time authority, and a time display for displaying a running real-time display time calculated as the trusted time from the secure clock plus the stored time value in the time offset. Reference thus may be made to the secure clock to evaluate a temporal requirement without concern that the user has adjusted the secure clock to subvert the temporal requirement. The computing device sends a request for secure time and the trusted time authority sends same. The computing device receives the secure time, sets the secure clock according to same, and sends confirmation to the trusted time authority that the secure time has been received.

摘要： A computing device displays a user interface containing a ribbon-shaped user interface. The ribbon-shaped user interface contains multiple tabs. Each of the tabs contains multiple controls. Furthermore, a challenge and a tab visualization control are displayed in the user interface. The challenge instructs a user of the computing device to perform a task using the ribbon-shaped user interface without instructing the user how to perform the task. In response to receiving selection of the tab visualization control, the computing device displays a popup window in the user interface. The popup window initially contains an image of an initial portion of a given tab in the ribbon-shaped user interface. The image of the given tab is scrolled within the popup window such that a target control in the given tab is visible within the popup window.

摘要： A device has a symmetric device key (DK) and a copy of (DK) encrypted according to a public key (PU) of an entity (PU(DK)). The device receives an object from a host computer, at least a portion of which is encrypted according to (DK). The device sends (PU(DK)) to the host computer, and the host computer sends (PU(DK)) to the entity. The entity applies a corresponding private key (PR) to (PU(DK)) to obtain (DK) and sends (DK) to the host computer. The host computer may then encrypt the object according to (DK) and download same to the device, and the device may decrypt the encrypted object based on (DK).
