CloViS : a Secured Cloud Virtualized Storage
Résumé
Cloud data storage may be used in different cases: for backup purpose, for hosted services or due to the virtualization of servers. Whatever the reason, the data may be secured according to three criteria: availability, integrity and confidentiality. These criteria are fundamental to establish a trust relationship between the customer and the provider. However, enforcing some of these constraints may have a significant cost, and even weaken other of these requirements. Thus, the main difficult task is to balance between opposite constraints depending on the service paid by the client. To overcome this problem, we propose the use of a storage virtualization middleware, named CloViS. This software layer allows pluggable QoS libraries to be used to implement the required security mechanisms.
