Abstract
Official abstract text for this publication.
Example embodiments of the present invention relate to a system, apparatus and methods for preserving the integrity of a code to prevent it from being modified, maliciously or inadvertently, while it is in execution in the RAM of a computer platform. This method also may be referred to as code hardening. Code to be hardened in example embodiments of the present invention may be referred to as protected code. Example embodiments of the present invention are able to externally detect unauthorized stoppage of the hypervisor by employing ( 1 ) a launch-time metric of the protected code; ( 2 ) a run-time metric of the protected code; and ( 3 ) a liveliness indicator of the protected code.
First claim
Opening claim text (preview).
What is claimed is: 1. A computer-implemented method comprising: receiving, from a computer platform at an external verifier, a launch-time metric of stored protected code, wherein the launch-time metric comprises a first measurement of stored protected code in storage of the computer platform generated at a first launch time of the computer platform; obtaining, from the computer platform at the external verifier, a run-time metric of the executed protected code, wherein the run…
