An Algorithm to Secure Virtual Machine Image in Cloud Environment

Virtual Machine is a combined form of operating system and application. Virtualization provides the facility to run multiple operating systems on a single physical machine. These multiple operating systems are called guest operating systems. In server Virtualization many virtual machines (VMs) can run on one server including its own server. These VMs can be migrated from one server to another. As VM image will be downloaded to create a new virtual machine on the guest operating system it has some security problems. Unauthorized access can create the security issues like Malware injection. Due to which there is a need of scheme capable of providing encryption, malware detection, automatic patching to restore the image. In this paper an algorithm is proposed which is capable of providing solution to the above issues.
