Abstract
Cloud computing relies on secure and efficient virtualization. Software level security solutions compromise the performance of virtual machines (VMs), as a large amount of computational power would be utilized for running the security modules. Moreover, software solutions are only as secure as the level that they work on. For example a security module on a hypervisor cannot provide security in the presence of an infected hypervisor. It is a challenge for virtualization technology architects to enhance the security of VMs without degrading their performance. Currently available server machines are not fully equipped to support a secure VM environment without compromising on performance. A few hardware modifications have been introduced by manufactures like Intel and AMD to provide a secure VM environment with low performance degradation. In this paper we propose a novel memory…
