2012

On Secure and Precise IR-UWB Ranging

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

To provide high ranging precision in multipath environments, a ranging protocol should find the first arriving path, rather than the strongest path. We demonstrate a new attack vector that disrupts such precise Time-of-Arrival (ToA) estimation, and allows ...

Protecting Location Privacy: Optimal Strategy against Localization Attacks

Jean-Pierre Hubaux, Jean-Yves Le Boudec, Reza Shokri, Georgios Theodorakopoulos, Carmela González Troncoso

The mainstream approach to protecting the location-privacy of mobile users in location-based services (LBSs) is to alter the users' actual locations in order to reduce the location information exposed to the service provider. The location obfuscation algor ...

Quantifying Location Privacy: The Case of Sporadic Location Exposure

Jean-Pierre Hubaux, Jean-Yves Le Boudec, Reza Shokri, Georgios Theodorakopoulos

Mobile users expose their location to potentially untrusted entities by using location-based services. Based on the frequency of location exposure in these applications, we divide them into two main types: Continuous and Sporadic. These two location exposu ...

OREN: Optimal Revocations in Ephemeral Networks

Jean-Pierre Hubaux, Maxime Raya, Igor Bilogrevic

Public-key certificates allow a multitude of entities to securely exchange and verify the authenticity of data. However, the ability to effectively revoke compromised or untrustworthy certificates is of great importance when coping with misbehavior. In thi ...

Collaborative Location Privacy with Rational Users

Jean-Pierre Hubaux, Mathias Jacques Jean-Marc Humbert, Reza Shokri, Francisco De Meneses Neves Ramos Dos Santos

Recent smartphones incorporate embedded GPS devices that enable users to obtain geographic information about their surroundings by providing a location-based service (LBS) with their current coordinates. However, LBS providers collect a significant amount ...

Collaborative Location Privacy

Jean-Pierre Hubaux, Panagiotis Papadimitratos, Reza Shokri, Georgios Theodorakopoulos

Location-aware smart phones support various location-based services (LBSs): users query the LBS server and learn on the fly about their surroundings. However, such queries give away private information, enabling the LBS to identify and track users. We addr ...

Privacy in Mobile Computing for Location-Sharing-Based Services

Jean-Pierre Hubaux, Imad Aad, Igor Bilogrevic, Murtuza Jadliwala

Location-Sharing-Based Services (LSBS) complement Location-Based Services by using locations from a group of users, and not just individuals, to provide some contextualized service based on the locations in the group. However, there are growing concerns ab ...

The Inconvenient Truth about Web Certificates

Jean-Pierre Hubaux, Julien Freudiger, Nevena Vratonjic, Vincent Bindschaedler

HTTPS is the de facto standard for securing Internet communications. Although it is widely deployed, the security provided with HTTPS in practice is dubious. HTTPS may fail to provide security for multiple reasons, mostly due to certificate-based authentic ...

Quantifying Location Privacy

Jean-Pierre Hubaux, Jean-Yves Le Boudec, Reza Shokri, Georgios Theodorakopoulos

It is a well-known fact that the progress of personal communication devices leads to serious concerns about privacy in general, and location privacy in particular. As a response to these issues, a number of Location-Privacy Protection Mechanisms (LPPMs) ha ...

Evaluating the Privacy Risk of Location-Based Services

Jean-Pierre Hubaux, Julien Freudiger, Reza Shokri

In modern mobile networks, users increasingly share their location with third-parties in return for location-based services. In this way, users obtain services customized to their location. Yet, such communications leak location information about users. Ev ...

Optimizing Mixing in Pervasive Networks: A Graph-Theoretic Perspective

Jean-Pierre Hubaux, Igor Bilogrevic, Murtuza Jadliwala

One major concern in pervasive wireless applications is location privacy, where malicious eavesdroppers, based on static device identifiers, can continuously track users. As a commonly adopted countermeasure to prevent such identifier-based tracking, devic ...
