On Data-Centric Trust Establishment in Ephemeral Ad Hoc Networks

Jean-Pierre Hubaux, Panagiotis Papadimitratos, Maxime Raya

We argue that the traditional notion of trust as a relation among entities, while useful, becomes insu±cient in ephemeral ad hoc networks. In this paper, we address the challenge of extending the traditional notion of trust to data-centric trust, that is, ...

TraNS: Realistic Joint Traffic and Network Simulator for VANETs

Jean-Pierre Hubaux, Matthias Grossglauser, Panagiotis Papadimitratos, Maxime Raya, Ada Lezama Lugo

Realistic simulation is a necessary tool for the proper evaluation of newly developed protocols for Vehicular Ad Hoc Networks (VANETs). Several recent efforts focus on achieving this goal. Yet, to this date, none of the proposed solutions fulfill all the r ...

Mix-Zones for Location Privacy in Vehicular Networks

Jean-Pierre Hubaux, Panagiotis Papadimitratos, Julien Freudiger, Mark Felegyhazi, Maxime Raya

Vehicular Networks (VNs) seek to provide, among other applications, safer driving conditions. To do so, vehicles need to periodically broadcast safety messages providing precise position information to nearby vehicles. However, this frequent messaging (e.g ...

Architecture for Secure and Private Vehicular Communications

Jean-Pierre Hubaux, Panagiotis Papadimitratos, Levente Buttyan, Maxime Raya

The deployment of vehicular communication (VC) systems is strongly dependent on their security and privacy features. In this paper, we propose a security architecture for VC. The primary objectives of the architecture include the management of identities a ...

Eviction of Misbehaving and Faulty Nodes in Vehicular Networks

Jean-Pierre Hubaux, Imad Aad, Panagiotis Papadimitratos, Maxime Raya, Daniel Jungels

Vehicular Networks (VNs) are emerging, among civilian applications, as a convincing instantiation of the mobile networking technology. However, security is a critical factor and a significant challenge to be met. Misbehaving or faulty network nodes have to ...

Securing Vehicular Ad Hoc Networks

Jean-Pierre Hubaux, Maxime Raya

Vehicular networks are very likely to be deployed in the coming years and thus become the most relevant form of mobile ad hoc networks. In this paper, we address the security of these networks. We provide a detailed threat analysis and devise an appropriat ...

DOMINO: Detecting MAC layer greedy behavior in IEEE 802.11 hotspots

Jean-Pierre Hubaux, Alaeddine El Fawal, Imad Aad, Maxime Raya

IEEE 802.11 works properly only if the stations respect the MAC protocol. We show in this paper that a greedy user can substantially increase his share of bandwidth, at the expense of the other users, by slightly modifying the driver of his network adapter ...

Efficient secure aggregation in VANETs

Jean-Pierre Hubaux, Adel Aziz, Maxime Raya

In VANETs, better communication efficiency can be achieved by sacrificing security and vice versa. But VANETs cannot get started without either of them. In this paper, we propose a set of mechanisms that can actually reconcile these two contradictory requi ...

Securing Vehicular Communications

Jean-Pierre Hubaux, Panagiotis Papadimitratos, Maxime Raya

The road to a successful introduction of vehicular communications has to pass through the analysis of potential security threats and the design of a robust security architecture able to cope with these threats. In this paper, we undertake this challenge. I ...
