ReplicaTEE: Enabling Seamless Replication of SGX Enclaves in the Cloud [article]

Claudio Soriente, Ghassan Karame, Wenting Li, Sergey Fedorov
2018 arXiv   pre-print
In this paper, we propose ReplicaTEE, a solution that enables seamless provisioning and decommissioning of TEE-based applications in the cloud.  ...  ReplicaTEE leverages an SGX-based provisioning layer that interfaces with a Byzantine Fault-Tolerant storage service to securely orchestrate enclave replication in the cloud, without the active intervention  ...  ReplicaTEE therefore emerges as the first secure and practical solution to support elasticity of TEE-based applications in the cloud.  ...

Data Privacy in Trigger-Action Systems [article]

Yunang Chen, Amrita Roy Chowdhury, Ruizhe Wang, Andrei Sabelfeld, Rahul Chatterjee, Earlence Fernandes
2021 arXiv   pre-print
Based on ten existing rules that exercise a wide variety of operations, we show that eTAP has a modest performance impact: on average rule execution latency increases by 70 ms (55%) and throughput reduces  ...  We use garbled circuits as a primitive, and leverage the unique structure of trigger-compute-action rules to make them practical. We formally state and prove the security guarantees of our protocols.  ...  This work was also partially supported by the Swedish Foundation for Strategic Research (SSF) and the Swedish Research Council (VR).  ...
