摘要： An apparatus and method for unilaterally loading a secure operating system within a multiprocessor environment are described. The method includes disregarding a received load secure region instruction when a currently active load secure region operation is detected. Otherwise, a memory protection element is directed, in response to the received load secure region instruction, to form a secure memory environment. Once directed, unauthorized read/write access to one or more protected memory regions are prohibited. Finally, a cryptographic hash value of the one or more protected memory regions is stored within a digest information repository as a secure software identification value. Once stored, outside agents may request access to a digitally signed software identification value in order to establish security verification of secure software within the secure memory environment.

摘要： A method and apparatus is provided for securing a region in a memory of a computer. According to one embodiment, the method comprises halting of all but one of a plurality of processors in a computer. The halted processors entering into a special halted state. Content is loaded into the region only after the halting of all but the one of the plurality of processors and the region is protected from access by the halted processors. The method further comprises placing the non-halted processor into a known privileged state, and causing the halted processors to exit the halted state after the non-halted processor has been placed into the known privileged state.

摘要： A method and apparatus is provided in which a trustable operating system is loaded into a region in memory. A start secure operation (SSO) triggers a join secure operation (JSO) to halt all but one central processing unit (CPU) in a multi-processor computer. The SSO causes the active CPU to load a component of an operating system into a specified region in memory, register the identity of the loaded operating system by recording a cryptographic hash of the contents of the specified region in memory, begin executing at a known entry point in the specified region and trigger the JSO to cause the halted CPUs to do the same.
