Security Games in Online Advertising: Can Ads Help Secure the Web?

Jean-Pierre Hubaux, Maxime Raya, Nevena Vratonjic

Some ISPs are trying to become part of the online advertising market. Such ISPs either: (i) cooperate with online advertising entities (e.g., ad networks) by providing users’ private information to achieve better ad targeting in exchange for a share of the ...

Unraveling an Old Cloak: k-anonymity for Location Privacy

Jean-Pierre Hubaux, Julien Freudiger, Reza Shokri, Carmela González Troncoso

There is a rich collection of literature that aims at protecting the privacy of users querying location-based services. One of the most popular location privacy techniques consists in cloaking users' locations such that k users appear as potential senders ...

Joint Sink Mobility and Routing to Maximize the Lifetime of Wireless Sensor Networks: The Case of Constrained Mobility

Jean-Pierre Hubaux, Jun Luo

The longevity of wireless sensor networks (WSNs) is a major issue that impacts the application of such networks. While communication protocols are striving to save energy by acting on sensor nodes, recent results show that network lifetime can be prolonged ...

The Cicada Attack: Degradation and Denial of Service in IR Ranging

Jean-Pierre Hubaux, Jean-Yves Le Boudec, Manuel Flury, Marcin Poturalski, Panagiotis Papadimitratos

We demonstrate that an interferer with malicious intentions can significantly degrade the performance of impulse radio (IR) ranging. The cicada attack we have developed can decrease the distance (degradation of service) measured by ranging algorithms desig ...

On the Age of Pseudonyms in Mobile Ad Hoc Networks

Jean-Pierre Hubaux, Jean-Yves Le Boudec, Julien Freudiger

In many envisioned mobile ad hoc networks, nodes are expected to periodically beacon to advertise their presence. In this way, they can receive messages addressed to them or participate in routing operations. Yet, these beacons leak information about the n ...

A Randomized Countermeasure Against Parasitic Adversaries in Wireless Sensor Networks

Jean-Pierre Hubaux, Jun Luo, Panagiotis Papadimitratos

Due to their limited capabilities, wireless sensor nodes are subject to physical attacks that are hard to defend against. In this paper, we first identify a typical attacker, called parasitic adversary, who seeks to exploit sensor networks by obtaining mea ...

Optimal Revocations in Ephemeral Networks: A Game-Theoretic Framework

Jean-Pierre Hubaux, Maxime Raya, Igor Bilogrevic

Revocation of public-key certificates is an important security primitive. In this paper, we design a fully distributed local certificate revocation scheme for ephemeral networks - a class of extremely volatile wireless networks with short-duration and shor ...

Tracking Games in Mobile Networks

Jean-Pierre Hubaux, Julien Freudiger, Mathias Jacques Jean-Marc Humbert

Users of mobile networks can change their identifiers in regions called mix zones in order to defeat the attempt of third parties to track their location. Mix zones must be deployed carefully in the network to reduce the cost they induce on mobile users an ...

Integrity of the Web Content: The Case of Online Advertising

Jean-Pierre Hubaux, Julien Freudiger, Nevena Vratonjic

Online advertising is a major source of revenues in the Internet. In this paper, we identify a number of vulnerabilities of current ad serving systems. We describe how an adversary can exploit these vulnerabilities to divert part of the ad revenue stream f ...

On the Tradeoff between Trust and Privacy in Wireless Ad Hoc Networks

Jean-Pierre Hubaux, Maxime Raya, Reza Shokri

As privacy moves to the center of attention in networked systems, and the need for trust remains a necessity, an important question arises: How do we reconcile the two seemingly contradicting requirements? In this paper, we show that the notion of data-cen ...

Effectiveness of Distance-Decreasing Attacks Against Impulse Radio Ranging

Jean-Pierre Hubaux, Jean-Yves Le Boudec, Manuel Flury, Marcin Poturalski, Panagiotis Papadimitratos

We expose the vulnerability of an emerging wireless ranging technology, impulse radio ultra-wide band (IR-UWB), to distance-decreasing attacks on the physical communication layer (PHY). These attacks violate the security of secure ranging protocols that al ...

Private Sharing of User Location over Online Social Networks

Jean-Pierre Hubaux, Julien Freudiger, Raoul Neu

Online social networks increasingly allow mobile users to share their location with their friends. Much to the detriment of users’ privacy, this also means that social network operators collect users’ lo- cation. Similarly, third parties can learn users’ l ...

Analysis and Optimization of Cryptographically Generated Addresses

Jean-Pierre Hubaux, Joppe Willem Bos, Onur Özen

The need for nodes to be able to generate their own address and verify those from others, without relying on a global trusted authority, is a well-known problem in networking. One popular technique for solving this problem is to use self-certifying address ...

Cooperation in Underwater Sensor Networks

Jean-Pierre Hubaux, Florent Frédéric Garcin

In underwater sensor networks (UWSNs), one of the main concerns is to reduce the energy consumption in order to maximize the lifetime. This work focuses on multiple sensor networks governed by different authorities. If the authorities are willing to cooper ...

Towards Privacy-Friendly Online Advertising

Jean-Pierre Hubaux, Julien Freudiger, Nevena Vratonjic

Modern web sites commonly interact with third-party domains to integrate advertisements and generate revenue from them. To improve the relevance of advertisement, online advertisers track user activities online with third- party cookies. However, excessive ...

Adaptive Message Authentication for Vehicular Networks

Jean-Pierre Hubaux, Jean-Yves Le Boudec, Panagiotis Papadimitratos, Nikodin Ristanovic, Georgios Theodorakopoulos

Public key cryptography can introduce significant processing delays in vehicular communication platforms. This can lead to serious performance issues, especially in the case of multi-hop Inter-Vehicle Communication. In this paper we propose Adaptive Messag ...

Efficient MAC in cognitive radio systems: A game-theoretic approach

Jean-Pierre Hubaux, Mario Cagalj, Mark Felegyhazi

In this paper, we study the problem of efficient medium access control (MAC) among cognitive radio devices that are equipped with multiple radios and thus are capable of transmitting simultaneously at different frequencies (channels). We assume that radios ...

A Distortion-based Metric for Location Privacy

Jean-Pierre Hubaux, Julien Freudiger, Reza Shokri, Murtuza Jadliwala

We propose a novel framework for measuring and evaluating location privacy preserving mechanisms in mobile wireless networks. Within this framework, we first present a formal model of the system, which provides an efficient representation of the network us ...

Preserving Privacy in Collaborative Filtering through Distributed Aggregation of Offline Profiles

Jean-Pierre Hubaux, Pedram Pedarsani, Reza Shokri, Georgios Theodorakopoulos

In recommender systems, usually, a central server needs to have access to users' profiles in order to generate useful recommendations. Having this access, however, undermines the users' privacy. The more information is revealed to the server on the user-it ...
