While on the one hand unresolved security issues pose a barrier to the widespread adoption of cloud computing technologies, on the other hand the computing capabilities of even commodity HW are boosting, in particular thanks to the adoption of -core technologies. For instance, the Nvidia Compute Unified Device Architecture (CUDA) technology is increasingly available on a large part of commodity hardware. In this paper, the authors show that it is possible to effectively use such a technology to guarantee an increased level of security to cloud hosts, services, and finally to the user. Secure virtualization is the key enabling factor. It can protect such resources from attacks.
