Abstract

The convergence of virtualization with Cloud computing has brought many benefits to organizations including ease of deployment, reduced costs and high availability of resources over internet. Extensive research has been carried out to increase the security of Cloud virtualization environment. However, addressing the security concerns of disk images used by virtual machines is still an open challenge. Compromising the disk images can result in loss of data integrity and confidentiality. This paper proposes a novel security scheme "Encrypted Virtual Disk Images in Cloud (EVDIC)" for the protection of stored disk images in Cloud by encryption. EVDIC also includes the security of key management and key exchange process. We integrate EVDIC with OpenStack, which is an open source Cloud platform largely used around the world.
