Toward Live Migration of SGX-Enabled Virtual Machines

Abstract

Intel Software Guard Extensions (SGX) can address the information disclosure in cloud computing. However, the existing virtual machine managers do not provide the efficient management operations of the SGX-enabled virtual machines (VMs) like live migration. In this paper, we identify challenges and propose a novel approach and its implementation model to migrate the SGX-enabled VMs. As future work, we will design the protocol and new instructions for live migration of the SGX-enabled VMs, and implement them on top of OpenSGX, an open source SGX emulator.
