Method, apparatus, and system for dynamic management of integrity-protected memory

Abstract

In certain aspects of the disclosure, an apparatus, comprises a first memory having a plurality of bits. Each bit of the plurality of bits of the first memory is associated with a region of a second memory, and each bit indicates whether the associated region of the second memory is to be integrity-protected. The first memory further stores a first minimum set of data necessary for integrity protection (MSD) of an associated first integrity protection tree when a first bit of the plurality of bits is set to a value indicating that the first associated region of the second memory is to be integrity-protected. Regions of the second memory that are integrity-protected may be non-contiguous, and may be adjusted during run-time.

Dependencies are inferred from the claim text.
