Privacy-preserving genotype imputation in a trusted execution environment. [PDF]
Cell Syst, 2021 AbstractGenotype imputation is an essential tool in genetics research, whereby missing genotypes are inferred based on a panel of reference genomes to enhance the power of downstream analyses. Recently, public imputation servers have been developed to allow researchers to leverage increasingly large-scale and diverse genetic data repositories for ...

A Design and Verification Methodology for a TrustZone Trusted Execution Environment [PDF]
IEEE Access, 2020 Hardware support for isolated execution (e.g., ARM TrustZone) enables the development of a trusted execution environment (TEE) that ensures the security of the code and data while communicating with a compromised rich execution environment (REE).

Profiling with trust: system monitoring from trusted execution environments [PDF]
Design Automation for Embedded Systems, 2023 Abstract Large-scale attacks on IoT and edge computing devices pose a significant threat. As a prominent example, Mirai is an IoT botnet with 600,000 infected devices around the globe, capable of conducting effective and targeted DDoS attacks on (critical) infrastructure.

Building Open Trusted Execution Environments
IEEE Security & Privacy, 2020 Trusted execution environments (TEEs) are a growing part of the security ecosystem. Unfortunately, widely available TEEs are hampered by closed designs and a lack of flexibility. We outline the challenges to TEEs, advocate for extensible and portable open TEEs, and detail current efforts.

Trusted Execution Environments: Applications and Organizational Challenges
Frontiers in Computer Science, 2022 A lack of trust in the providers is still a major barrier to cloud computing adoption – especially when sensitive data is involved. While current privacy-enhancing technologies, such as homomorphic encryption, can increase security, they come with a ...

On (the Lack of) Code Confidentiality in Trusted Execution Environments
2024 IEEE Symposium on Security and Privacy (SP), 2022 Trusted Execution Environments (TEEs) have been proposed as a solution to protect code confidentiality in scenarios where computation is outsourced to an untrusted operator. We study the resilience of such solutions to side-channel attacks in two commonly deployed scenarios: when a confidential code is a native binary that is shipped and executed ...

TS-Perf: General Performance Measurement of Trusted Execution Environment and Rich Execution Environment on Intel SGX, Arm TrustZone, and RISC-V Keystone [PDF]
IEEE Access, 2021 A trusted execution environment (TEE) is a new hardware security feature that is isolated from a normal OS (i.e., rich execution environment (REE)). The TEE enables us to run a critical process, but the behavior is invisible from the normal OS, which ...
