Patent number: 8281338Abstract: Detailed herein is a technology which, among other things, allows for storage and playback of interactive user elements in a television stream. In one approach to this technology, a content data stream, including a television program and a user experience element, is received. This content data stream is transformed, and the transformed data stream is examined, to identify which packets are associated with the user experience element. Those packets are then passed to a handler appropriate for the user experience element.Type: GrantFiled: February 27, 2007Date of Patent: October 2, 2012Assignee: Microsoft CorporationInventors: Gabe Gottlieb, Ken Reneris

Patent number: 7389427Abstract: A method and platform for maintaining the security of output data in an isolated execution environment. A system memory has an isolated output area readable only by secure output controllers having an isolated execution mode. The output controllers may make a request for access to the isolated output area, upon proper authentication if the request access is granted. The output device may either DMA the content of the isolated output area to an output end point, such as a display, or load it into local storage, the security of which is guaranteed by the controller.Type: GrantFiled: September 28, 2000Date of Patent: June 17, 2008Assignee: Intel CorporationInventors: Francis X.

Patent number: 7380278Abstract: A processing system has a processor that can operate in a normal ring 0 operating mode and one or more higher ring operating modes above the normal ring 0 operating mode. In addition, the processor can operate in an isolated execution mode. A memory in the processing system may include an ordinary memory area that can be accessed from the normal ring 0 operating mode, as well as an isolated memory area that can be accessed from the isolated execution mode but not from the normal ring 0 operating mode. The processing system may also include an operating system (OS) nub, as well as a key generator. The key generator may generate an OS nub key (OSNK) based at least in part on an identification of the OS nub and a master binding key (BK0) of the platform. Other embodiments are described and claimed.Type: GrantFiled: March 21, 2006Date of Patent: May 27, 2008Assignee: Intel CorporationInventors: Carl M. Ellison, Roger A. Golliver, Howard C.

Patent number: 7254707Abstract: In one embodiment, a method of attestation involves a special mode of operation. The method comprises storing an audit log within protected memory of a platform. The audit log is a listing of data representing one or more software modules loaded into the platform. The audit log is retrieved from the protected memory in response to receiving an attestation request. Then, the retrieved audit log is digitally signed to produce a digital signature in response to the attestation request.Type: GrantFiled: August 12, 2005Date of Patent: August 7, 2007Assignee: Intel CorporationInventors: Howard C.

Patent number: 7194634Abstract: In an embodiment of the present invention, a technique is provided for remote attestation. An interface maps a device via a bus to an address space of a chipset in a secure environment for an isolated execution mode. The secure environment is associated with an isolated memory area accessible by at least one processor. The at least one processor operates in one of a normal execution mode and the isolated execution mode. A communication storage corresponding to the address space allows the device to exchange security information with the at least one processor in the isolated execution mode in a remote attestation.Type: GrantFiled: February 26, 2001Date of Patent: March 20, 2007Assignee: Intel CorporationInventors: Carl M.

Patent number: 7111176Abstract: The present invention is a method and apparatus to generates an isolated bus cycle for a transaction in a processor. A configuration storage contains configuration parameters to configure a processor in one of a normal execution mode and an isolated execution mode. An access generator circuit generates an isolated access signal using at least one of the isolated area parameters and access information in the transaction. The isolated access signal is asserted when the processor is configured in the isolated execution mode. A bus cycle decoder generates an isolated bus cycle corresponding to a destination in the transaction using the asserted isolated access signal and the access information.Type: GrantFiled: March 31, 2000Date of Patent: September 19, 2006Assignee: Intel CorporationInventors: Carl M.
