PoCoFL: POlicy-COmpliant Federated Learning
Dominik Roy George, Varesh Mishra, Aysajan Abidin
Federated Learning (FL) is a privacy-oriented learning paradigm that enables collaborative model training while keeping training data local to participating clients. However, it do…
MOZAIK: A Privacy-Preserving Analytics Platform for IoT Data Using MPC and FHE
Michiel Van Kenhove, Erik Pohle, Leonard Schild +5
The rapid increase of Internet of Things (IoT) systems across several domains has led to the generation of vast volumes of sensitive data, presenting significant challenges in term…
Fast Evaluation of S-boxes with Garbled Circuits
Erik Pohle, Aysajan Abidin, Bart Preneel
Garbling schemes are vital primitives for privacy-preserving protocols and secure two-party computation. This paper presents a projective garbling scheme that assigns values…
Entanglement-based Mutual Quantum Distance Bounding
Aysajan Abidin, Karim Eldefrawy, Dave Singelee
Mutual distance bounding (DB) protocols enable two distrusting parties to establish an upper-bound on the distance between them. DB has been so far mainly considered in classical s…
Decentralized Privacy-Preserving Proximity Tracing
Carmela Troncoso, Mathias Payer, Jean-Pierre Hubaux +31
This document describes and analyzes a system for secure and privacy-preserving proximity tracing at large scale. This system, referred to as DP3T, provides a technological foundat…
Frictionless Authentication Systems: Emerging Trends, Research Challenges and Opportunities
Tim Van hamme, Vera Rimmer, Davy Preuveneers +4
Authentication and authorization are critical security layers to protect a wide range of online systems, services and content. However, the increased prevalence of wearable and mob…
Frictionless Authentication System: Security & Privacy Analysis and Potential Solutions
Mustafa A. Mustafa, Aysajan Abidin, Enrique Argones Rúa
This paper proposes a frictionless authentication system, provides a comprehensive security analysis of and proposes potential solutions for this system. It first presents a system…
Secure and Privacy-Friendly Local Electricity Trading and Billing in Smart Grid
Aysajan Abidin, Abdelrahaman Aly, Sara Cleemput +1
This paper proposes two decentralised, secure and privacy-friendly protocols for local electricity trading and billing, respectively. The trading protocol employs a bidding algorit…
A Secure and Privacy-preserving Protocol for Smart Metering Operational Data Collection
Mustafa A. Mustafa, Sara Cleemput, Abelrahaman Aly +1
In this paper we propose a novel protocol that allows suppliers and grid operators to collect users' aggregate metering data in a secure and privacy-preserving manner. We use secur…
Direct Proof of Security of Wegman-Carter Authentication with Partially Known Key
Aysajan Abidin, Jan-Åke Larsson
Information-theoretically secure (ITS) authentication is needed in Quantum Key Distribution (QKD). In this paper, we study security of an ITS authentication scheme proposed by Wegm…
