The increasing number of threats targeting cloud computing and the exploitation of
specifically privileged software vulnerabilities have pushed the security managers of cloud …

Data confidentiality is a central concern in modern computer systems and services, as
sensitive data from users and companies are being increasingly delegated to such systems …

This paper presents Protected Execution Facility (PEF), a virtual machine-based Trusted
Execution Environment (TEE) for confidential computing on Power ISA. PEF enables …

Scientific computing sometimes involves computation on sensitive data. Depending on the
data and the execution environment, the HPC (high-performance computing) user or data …

Pooling and sharing data increases and distributes its value. But since data cannot be
revoked once shared, scenarios that require controlled release of data for regulatory …

Protection of personal data has been raised to be among the top requirements of modern
systems. At the same time, it is now frequent that the owner of the data and the owner of the …

To operate efficiently across a wide range of workloads with varying power requirements, a
modern processor applies different current management mechanisms, which briefly throttle …

We propose a protocol that explores a synergy between two TEE implementations: it brings
SGX-like remote attestation to SEV VMs. We use the notion of a trusted guest owner …

Processing sensitive data, such as those produced by body sensors, on third-party untrusted
clouds is particularly challenging without compromising the privacy of the users generating …

The publish-subscribe paradigm is an efficient communication scheme with strong
decoupling between the nodes, that is especially fit for large-scale deployments. It adapts …
