Abstract
System and method for managing migration of trusted execution environments (TEEs) based on migration policies utilizes a source migration agent in the source host computer and a destination migration agent in a destination host computer to migrate a source TEE in the source host computer to the destination host computer. A migration policy data of the source TEE is first transmitted to the destination migration agent from the source migration agent to determine whether the destination host computer satisfies migration policies specified in the migration policy data. In response to a determination that the destination host computer satisfies the migration policies specified in the migration policy data, a destination TEE is created in the destination host computer and memory pages of the source TEE are transmitted to the destination TEE. The memory pages are then restored at the destination TEE for execution.
