Secure Content-Based Routing Using Intel Software Guard Extensions
TLDR
This work exploits Intel's new software guard extensions (SGX) to implement a CBR engine in a secure enclave and is the first to demonstrate the practical benefits of SGX for privacy-preserving CBR.
SGX-Aware Container Orchestration for Heterogeneous Clusters
TLDR
In insights regarding the support of SGX inside Kubernetes, an industry-standard container orchestrator, the architecture of the scheduler and its monitoring framework, the underlying operating system support and the required kernel driver extensions are provided.
Evaluation of an RSSI-based Location Algorithm for Wireless Sensor Networks
TLDR
This work shows an evaluation of an implementation of a location algorithm for wireless sensor networks and presents improvements that substantially improve the trustworthiness in its results.
SecureStreams: A Reactive Middleware Framework for Secure Data Stream Processing
TLDR
SecureStreams is introduced, a reactive middleware framework to deploy and process secure streams at scale that combines the high-level reactive dataflow programming paradigm with Intel's low-level software guard extensions (SGX) in order to guarantee privacy and integrity of the processed data.
Anonymous and Confidential File Sharing over Untrusted Clouds
TLDR
Results highlight that the A-SKY cryptographic scheme is 3 orders of magnitude better than state of the art ANOBE, and an end-to-end system encapsulating A- SKY can elastically scale to support groups of 10000 users while maintaining processing costs below 1 second.
SecureCloud: Secure big data processing in untrusted clouds
TLDR
To provide security guarantees, SecureCloud leverages novel security mechanisms present in recent commodity CPUs, in particular, Intel's Software Guard Extensions (SGX).
X-search: revisiting private web search using intel SGX
TLDR
X-Search is introduced, a novel private Web search mechanism building on the disruptive Software Guard Extensions (SGX) proposed by Intel and it is shown that it offers stronger privacy guarantees than its competitors as it operates under a stronger adversarial model.
Security, Performance and Energy Trade-Offs of Hardware-Assisted Memory Protection Mechanisms
TLDR
This paper implements and evaluates a publish/subscribe use-case and evaluates the impact of the memory protection mechanisms and the resulting performance and reports on the experience gained while building this system, in particular when having to cope with the technical limitations imposed by SEV and SGX.
A Lightweight MapReduce Framework for Secure Processing with SGX
TLDR
The use of Intel SGX for providing privacy guarantees for MapReduce operations is explored, and based on the evaluation it is concluded that it represents a viable alternative to a cryptographic mechanism.
CYCLOSA: Decentralizing Private Web Search through SGX-Based Browser Extensions
TLDR
CYCLOSA proposes a novel adaptive privacy protection solution that reduces the risk of user re-identification and achieves accuracy of Web search as it handles the real query and the fake queries separately, in contrast to other existing solutions that mix fake and real query results.
