Selecting Trustworthy Clients in the Cloud

Selecting Trustworthy Content using Tags

Networked portable devices enable their users to easily create and share digital content (e.g., photos, videos). Hitherto, this serendipitous form of sharing has not happened. That may be because, for sharing content, mobile users have no choice but to go through the Internet. Users are thus in need of decentralised mechanisms for browsing location-based content. To realize such mechanisms, the...

Selecting Trustworthy Service in Service-Oriented Environments

Most of current service selection approaches in service-oriented environments fail to capture the dynamic relationships between services or assume the complete knowledge of service composition is known as a prior. In these cases, problems may arise when consumers are not aware of the underlying composition behind services. We propose a distributed trust-aware service selection model based on a ...

Transparent and Trustworthy Cloud

Towards Trustworthy Cloud Storage

The success of cloud computing is driven by the tremendous economic benefit offered to companies, private citizens and public administration to deploy, provision and use cloud services in a cost effective manner. The cloud is gaining increasing importance and applicability in numerous application domains. By shaping the way we access, store, and compute on data, the cloud offers a largely profi...

VC3: Trustworthy Data Analytics in the Cloud

We present VC3, the first system that allows users to run distributed MapReduce computations in the cloud while keeping their code and data secret, and ensuring the correctness and completeness of their results. VC3 runs on unmodified Hadoop, but crucially keeps Hadoop, the operating system and the hypervisor out of the TCB; thus, confidentiality and integrity are preserved even if these large ...
