Argos: Verifiable FHE Using Commodity Hardware
… fully homomorphic encryption (FHE) schemes using trusted hardware. Traditional approaches to verifiable FHE require expensive cryptographic proofs, which incur an overhead of up to seven orders of magnitude on top of FHE, making them impractical. With Argos, we show that trusted hardware can be …

Trustworthy History and Provenance for Files and Databases
… assurances for the history of data in an untrusted environment. We show that it is possible to provide strong integrity assurances for data history, without incurring high performance overheads, or using costly trusted hardware. We first focus on file systems and data provenance, and develop …

Hiding Decryption Latency in Intel SGX using Metadata Prediction
Hardware-Assisted Trusted Execution Environment technologies have become a crucial component in providing security for cloud-based computing. One of such hardware-assisted countermeasures is Intel Software Guard Extension (SGX). Using additional dedicated hardware and a new set of CPU instructions, …

Hardening Trusted Execution Environments Against Microarchitectural Side-Channel Attacks: A Constructive Approach
Trusted Execution Environments (TEEs) [1–5] promised to enable secure computation even in the presence of privileged adversaries by providing hardware-enforced isolation. However, the discovery of microarchitectural side-channel and transient execution attacks [6–10] has severely undermined these …

Secure Input Overlays : increasing security for sensitive data on Android
… an important part of people's lives. Often, an untrusted mobile application will need to obtain sensitive inputs, such as credit card information or passwords, from the user. The application needs these sensitive inputs in order to send them to a trusted service provider that enables the …
