DDH-based schemes for multi-party Function Secret Sharing
Marc Damie, Florian Hahn, Andreas Peter +1
Function Secret Sharing (FSS) schemes enable sharing efficiently secret functions. Schemes dedicated to point functions, referred to as Distributed Point Functions (DPFs), are the…
TOSSS: a CVE-based Software Security Benchmark for Large Language Models
Marc Damie, Murat Bilgehan Ertan, Domenico Essoussi +3
With their increasing capabilities, Large Language Models (LLMs) are now used across many industries. They have become useful tools for software engineers and support a wide range…
Secure Sparse Matrix Multiplications and their Applications to Privacy-Preserving Machine Learning
Marc Damie, Florian Hahn, Andreas Peter +1
To preserve data privacy, multi-party computation (MPC) enables executing Machine Learning (ML) algorithms on private data. However, MPC frameworks do not include optimized operati…
How to Securely Shuffle? A survey about Secure Shufflers for privacy-preserving computations
Marc Damie, Florian Hahn, Andreas Peter +1
Ishai et al. (FOCS'06) introduced secure shuffling as an efficient building block for private data aggregation. Recently, the field of differential privacy has revived interest in…
Energy Consumption of TLS, Searchable Encryption and Fully Homomorphic Encryption
Marc Damie, Mihai Pop, Merijn Posthuma
Privacy-enhancing technologies (PETs) have attracted significant attention in response to privacy regulations, driving the development of applications that prioritize user data pro…
Eliminating Exponential Key Growth in PRG-Based Distributed Point Functions
Marc Damie, Florian Hahn, Andreas Peter +1
Distributed Point Functions (DPFs) enable sharing secret point functions across multiple parties, supporting privacy-preserving technologies such as Private Information Retrieval,…
