ABSTRACT:
Methods of providing and limiting access to trusted memory are provided. Trusted memory pages are not mapped with page map pages. When a central processor is operated in a page-mapping mode, access to the trusted memory is limited. In particular, without mapping information, software and hardware modules cannot access and modify the contents of trusted memory sections.
