Secure Positioning in Wireless Networks

So far, the problem of positioning in wireless networks has been studied mainly in a nonadversarial setting. In this paper, we analyze the resistance of positioning techniques to position and distance spoofing attacks. We propose a mechanism for secure pos ...

Multi-radio Channel Allocation in Competitive Wireless Networks

Jean-Pierre Hubaux, Mario Cagalj, Mark Felegyhazi

Channel allocation has been extensively studied in the framework of cellular networks, but the emergence of new system concepts, such as cognitive radio systems, bring this topic into the focus of research again. In this paper, we provide a formal analysis ...

Securing Wireless Mesh Networks

Jean-Pierre Hubaux, Naouel Ben Salem

Using wireless mesh networks to offer Internet connectivity is becoming a popular choice for wireless Internet service providers as it allows fast, easy, and inexpensive network deployment. However, security in WMNs is still in its infancy as very little a ...

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 ...

COMMON-Sense Net: Improved Water Management for Resource-Poor Farmers via Sensor Networks

Jean-Pierre Hubaux, Jacques Panchard

We describe the on-going design and implementation of a sensor network for agricultural management targeted at resource-poor farmers in India. Our focus on semi-arid regions led us to concentrate on water-related issues. Throughout 2004, we carried outa su ...

Non-Interactive Location Surveying for Sensor Networks with Mobility-Differentiated ToA

Jean-Pierre Hubaux, Jun Luo, Hersh Vardhan Shukla

Location-awareness is crucial to many applications of sensor networks. Existing location surveying approaches either rely on an inflexible infrastructure or suffer from high computation and communication load. In this paper, we present Non-intEractive lOca ...

Integrity (I) codes: Message Integrity Protection and Authentication over Insecure Channels

Jean-Pierre Hubaux, Srdan Capkun, Mario Cagalj

Inspired by unidirectional error detecting codes that are used in situations where only one kind of bit errors are possible (e.g., it is possible to change a bit “0” into a bit “1”, but not the contrary), we propose integrity codes (I-codes) for a radio co ...

MobiRoute: Routing towards a Mobile Sink for Improving Lifetime in Sensor Networks

Jean-Pierre Hubaux, Jacques Panchard, Jun Luo, Matthias Grossglauser

Improving network lifetime is an important issue involved in every aspect of the design and deployment of wireless sensor networks. There is a recent research trend of studying the application of a mobile sink to transport (rather than let the sensor nodes ...

Privacy and Identity Management for Vehicular Communication Systems: a Position Paper

Jean-Pierre Hubaux, Panagiotis Papadimitratos

The emerging technology of vehicular communications (VC) raises a number of technical problems that need to be addressed. Among those, security and privacy concerns are paramount for the wide adoption of VC. In this position paper, we are concerned with pr ...

Nash Equilibria of Packet Forwarding Strategies in Wireless Ad Hoc Networks

Jean-Pierre Hubaux, Levente Buttyan, Mark Felegyhazi

In self-organizing ad hoc networks, all the networking functions rely on the contribution of the participants. As a basic example, nodes have to forward packets for each other in order to enable multi-hop communication. In recent years, incentive mechanism ...

Key Agreement in Peer-to-Peer Wireless Networks

Jean-Pierre Hubaux, Srdan Capkun, Mario Cagalj

We present a set of simple techniques for key establishment over a radio link in peer-to-peer networks. Our approach is based on the Diffie-Hellman key agreement protocol, which is known to be vulnerable to the ``man-in-the-middle" attack if the two users ...

Mobility Helps Peer-to-Peer Security

Jean-Pierre Hubaux, Levente Buttyan, Srdan Capkun

We propose a straightforward technique to provide peer-to-peer security in mobile networks. We show that far from being a hurdle, mobility can be exploited to set up security associations among users. We leverage on the temporary vicinity of users, during ...

How to Specify and How to Prove Correctness of Secure Routing Protocols for MANET

Jean-Pierre Hubaux, Panagiotis Papadimitratos

Secure routing protocols for mobile ad hoc networks have been developed recently, yet, it has been unclear what are the properties they achieve, as a formal analysis of these protocols is mostly lacking. In this paper, we are concerned with this problem, h ...

Node Cooperation in Hybrid Ad hoc Networks

Jean-Pierre Hubaux, Levente Buttyan, Naouel Ben Salem

A hybrid ad hoc network is a structure-based network that is extended using multi-hop communications. Indeed, in this kind of network, the existence of a communication link between the mobile station and the base station is not required: A mobile station t ...

Reputation-based Wi-Fi Deployment

Jean-Pierre Hubaux, Naouel Ben Salem

Wi-Fi networks have a very strong potential: They are easy to deploy, they use unlicensed frequencies and they provide Internet connectivity that is several times faster than by cable modem. However, two major problems still need to be solved: the lack of ...

A Fair Scheduling for Wireless Mesh Networks

Jean-Pierre Hubaux, Naouel Ben Salem

Wireless Mesh Networks (WMNs) represent a new and promising paradigm that uses multi-hop communications to extend WiFi networks: By deploying only one hot spot (directly connected to the Internet) and several transient access points (TAPs), an Internet Ser ...
