Secure and Efficient Migration of Large Enclaves in a Data Center

Cloud service providers are increasingly adopting Trusted Execution Environments, or TEEs, to provide hardware guaranteed security to an application executing on remote, untrusted data centers. Often, there is a need to live-migrate such secure applications for load balancing or data center maintenance. Today, state-of-the-art migration methods for TEE still use the decade-old stop-and-copy-based method, which introduces large downtimes. This is because state-of-the-art live-migration approaches do not work for applications that run on TEEs.
