Correctness verification of query results is a significant challenge in database outsourcing. Most of the proposed approaches impose high overhead, which makes them impractical in real scenarios. Probabilistic approaches are proposed in order to reduce the computation overhead pertaining to the verification process. In this paper, we use the notion of trust as the basis of our probabilistic app...

The adoption of the cloud computing paradigm is associated with increasing security concerns. Cloud computing service models (SaaS, PaaS and IaaS) are exposed to different security threats in each level of services. The Trusted Cloud Computing Platform (TCCP) proposes a security model that protects customers VMs at the IaaS level. In this paper, we investigate methodologies for the specificatio...

Cloud Computing, i. e. providing on-demand access to virtualised computing resources over the Internet, is one of the current megatrends in IT. Today, there are already several providers offering cloud computing infrastructure (IaaS), platform (PaaS) and software (SaaS) services. Although the cloud computing paradigm promises both economical as well as technological advantages, many potential u...

Cloud computing, the long-held dream of computing as a utility, has finally came to realization. Cloud computing has the potential to transform a large part of the IT industry, making software even more attractive as a service and shaping the way IT hardware is designed and purchased.
