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.
