A Remote Attestation Approach for a Secure Virtual Machine Migration in Federated Cloud Environments

Nowadays, cloud computing is considered as a new charming technology, where new opportunities in ICT world are becoming real. Cloud is appealing many IT companies, but the largest business is in hand of big cloud operators. In the near future the scenario could change, and becoming much more complex even involving small and medium providers. Cloud operators could collaborate to satisfy the increasing cloud customer demand. The security is one of the main aspects that might limit such a collaboration. This paper deals with the opportunity to leverage the Trusted Computing technology for encouraging the federation in trustiness among heterogeneous clouds. In this work, we describe how Trusted Computing may increase the security in clouds, in particular when VM migration takes place between federated providers.
