摘要：Cloud computing provides a way to store andprocess information through a set of resources which might beaccessed on-line. Cloud may be a assortment of storage andphysical machines that are termed as datacenter. Cloudconsists of the many datacenters situated at geographicallycompletely different places. each physical machine ofdatacenter will handle more than one user. Virtualization isthat the technology behind the cloud to utilize the resources.Virtualization offers that a lot of virtual machines akin to eachtask of user are often submitted for execution on a similarphysical machine. The virtual machine can get destroyed asbefore long as task are going to be finished. To balance load ofthe cloud datacenters these virtual machines are migratedbetween physical machines. additionally the} virtual machineare often created by the VM image taken from the repositoryaccessible on-line also. So, this virtualization method impartsseveral threats to cloud computing model like VM imagesharing, VM isolation violation, VM escape. to overcome thesethreats a secure cloud computing model is planned during thiswork. This model includes a certification authority thatgenerated pair-wise keys for all physical machine and virtualmachines. Digital signature method is employed for eachcontrol message transmitted in cloud. and every one the VMsare encrypted using separate key. it's illustrated that plannedsecure cloud design doesn’t imparts a lot of overhead andprovides secure VM image sharing, secure VM migration andprovides security from VM escape and VM isolation problem.
