Abstract

A scheme for protecting policy state information during the lifetime of a virtual machine is presented. In order to protect and preserve the policy state information of the virtual machine, a process creates a source policy, a mapping policy, and a binary policy. These policies are all different representations of a security policy. The different policy representations are chained together via cryptographic hashes.
