FedRings: A Scalable and Topology-Aware Federated Learning Framework for LEO Satellite Constellations
Ziwu Liu, Inês Pinto Gouveia, Rehana Yasmin +2
Federated learning over low Earth orbit (LEO) satellite networks is limited by frequent link changes, short contact times, and a highly dynamic topology, making centralized or sync…
Toward Space-Based Public Key Systems: Enabling Secure Space Communications through In-Orbit Trust Services
Rehana Yasmin, Paulo Esteves-Verissimo, Ali Shoker
The New Space era has led to a rapid increase in satellites operated by independent entities in near-Earth orbit. This shift enables richer space services but also requires secure,…
EVSOAR: Security Orchestration, Automation and Response via EV Charging Stations
Tadeu Freitas, Erick Silva, Rehana Yasmin +4
Vehicle cybersecurity has emerged as a critical concern, driven by the innovation in the automotive industry, e.g., automomous, electric, or connnected vehicles. Current efforts to…
EVOLVE: a Value-Added Services Platform for Electric Vehicle Charging Stations
Erick Silva, Tadeu Freitas, Rehana Yasmin +2
A notable challenge in Electric Vehicle (EV) charging is the time required to fully charge the battery, which can range from 15 minutes to 2-3 hours. This idle period, however, pre…
ResiLogic: Leveraging Composability and Diversity to Design Fault and Intrusion Resilient Chips
Ahmad T. Sheikh, Ali Shoker, Suhaib A. Fahmy +1
A long-standing challenge is the design of chips resilient to faults and glitches. Both fine-grained gate diversity and coarse-grained modular redundancy have been used in the past…
Resilient and Secure Programmable System-on-Chip Accelerator Offload
Inês Pinto Gouveia, Ahmad T. Sheikh, Ali Shoker +2
Computational offload to hardware accelerators is gaining traction due to increasing computational demands and efficiency challenges. Programmable hardware, like FPGAs, offers a pr…

Xingyu Su, Xiaojie Zhu, Yang Li +3
Amidst the surge in deep learning-based password guessing models, challenges of generating high-quality passwords and reducing duplicate passwords persist. To address these challen…
Savvy: Trustworthy Autonomous Vehicles Architecture
Ali Shoker, Rehana Yasmin, Paulo Esteves-Verissimo
The increasing interest in Autonomous Vehicles (AV) is notable due to business, safety, and performance reasons. While there is salient success in recent AV architectures, hinging…
Vivisecting the Dissection: On the Role of Trusted Components in BFT Protocols
Alysson Bessani, Miguel Correia, Tobias Distler +3
A recent paper by Gupta et al. (EuroSys'23) challenged the usefulness of trusted component (TC) based Byzantine fault-tolerant (BFT) protocols to lower the replica group size from…
ScalOTA: Scalable Secure Over-the-Air Software Updates for Vehicles
Ali Shoker, Fernando Alves, Paulo Esteves-Verissimo
Over-the-Air (OTA) software updates are becoming essential for electric/electronic vehicle architectures in order to reduce recalls amid the increasing software bugs and vulnerabil…
System on Chip Rejuvenation in the Wake of Persistent Attacks
Ahmad T Sheikh, Ali Shoker, Paulo Esteves-Verissimo
To cope with the ever increasing threats of dynamic and adaptive persistent attacks, Fault and Intrusion Tolerance (FIT) is being studied at the hardware level to increase critical…
