Empirical Analysis of TEE-Enabled Rollup Designs
Claudiu-Nicu Bărbieru, Corentin Libert, Peterson Yuhala +7
Layer 2 (L2) rollups have become the dominant scaling solution in Ethereum. At the core of these systems lies the rollup sequencer, a component that orders, executes, and submits L…
PIM-CACHE: High-Efficiency Content-Aware Copy for Processing-In-Memory
Peterson Yuhala, Mpoki Mwaisela, Pascal Felber +1
Processing-in-memory (PIM) architectures bring computation closer to data, reducing the processor-memory transfer bottleneck in traditional processor-centric designs. Novel hardwar…
DRAMatic Speedup: Accelerating HE Operations on a Processing-in-Memory System
Niklas Klinger, Jonas Sander, Peterson Yuhala +2
Homomorphic encryption (HE) is a promising technology for confidential cloud computing, as it allows computations on encrypted data. However, HE is computationally expensive and of…
IM-PIR: In-Memory Private Information Retrieval
Mpoki Mwaisela, Peterson Yuhala, Pascal Felber +1
Private information retrieval (PIR) is a cryptographic primitive that allows a client to securely query one or multiple servers without revealing their specific interests. In spite…
Practical Secure Aggregation by Combining Cryptography and Trusted Execution Environments
Romain de Laage, Peterson Yuhala, François-Xavier Wicht +3
Secure aggregation enables a group of mutually distrustful parties, each holding private inputs, to collaboratively compute an aggregate value while preserving the privacy of their…
Evaluating the Potential of In-Memory Processing to Accelerate Homomorphic Encryption
Mpoki Mwaisela, Joel Hari, Peterson Yuhala +3
The widespread adoption of cloud-based solutions introduces privacy and security concerns. Techniques such as homomorphic encryption (HE) mitigate this problem by allowing computat…
Fortress: Securing IoT Peripherals with Trusted Execution Environments
Peterson Yuhala, Jämes Ménétrey, Pascal Felber +2

A Holistic Approach for Trustworthy Distributed Systems with WebAssembly and TEEs
Jämes Ménétrey, Aeneas Grüter, Peterson Yuhala +4
Publish/subscribe systems play a key role in enabling communication between numerous devices in distributed and large-scale architectures. While widely adopted, securing such syste…
SecV: Secure Code Partitioning via Multi-Language Secure Values
Peterson Yuhala, Pascal Felber, Hugo Guiroux +4
Trusted execution environments like Intel SGX provide \emph{enclaves}, which offer strong security guarantees for applications. Running entire applications inside enclaves is possi…
Enhancing IoT Security and Privacy with Trusted Execution Environments and Machine Learning
Peterson Yuhala
With the increasing popularity of Internet of Things (IoT) devices, security concerns have become a major challenge: confidential information is constantly being transmitted (somet…
Montsalvat: Partitioning Java Applications to Minimize the TCB in Intel SGX
Peterson Yuhala, Jämes Ménétrey, Pascal Felber +5
The popularity of the Java programming language has led to its wide adoption in cloud computing infrastructures. However, Java applications running in untrusted clouds are vulnerab…
SGX Switchless Calls Made Configless
Peterson Yuhala, Michael Paper, Timothée Zerbib +3
Intel's software guard extensions (SGX) provide hardware enclaves to guarantee confidentiality and integrity for sensitive code and data. However, systems leveraging such security…
Plinius: Secure and Persistent Machine Learning Model Training
Peterson Yuhala, Pascal Felber, Valerio Schiavoni +1
