Abstract
A processing system has a processor that can operate in a normal ringoperating mode and one or more higher ring operating modes above the normal ringoperating 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 ringoperating mode, as well as an isolated memory area that can be accessed from the isolated execution mode but not from the normal ringoperating 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 (BK) of the platform. Other embodiments are described and claimed.
