Abstract
Techniques for memory compartmentalization for trusted execution of a virtual machine (VM) on a multi-core processing architecture are described. Memory compartmentalization may be achieved by encrypting layer 3 (L3) cache lines using a key under the control of a given VM within the trust boundaries of the processing core on which that VMs is executed. Further, embodiments described herein provide an efficient method for storing and processing encryption related metadata associated with each encrypt/decrypt operation performed for the L3 cache lines.
