Distributed Constraint Optimization

Thomas Léauté

Distributed Constraint Satisfaction (DisCSP) and Distributed Constraint Optimization (DCOP) are formal frameworks that can be used to model a variety of problems in which multiple decision-makers cooperate towards a common goal: from computing an equilibri ...

Privacy in Mobile Computing for Location-Sharing-Based Services

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

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 ...

On Tamper-Resistance from a Theoretical Viewpoint: The Power of Seals

Serge Vaudenay

Tamper-proof devices are pretty powerful. They can be used to have better security in applications. In this work we observe that they can also be maliciously used in order to defeat some common privacy protection mechanisms. We propose the theoretical mode ...

Mutual Authentication in RFID: Security and Privacy

Serge Vaudenay, Radu-Ioan Paise

In RFID protocols, tags identify and authenticate themselves to readers. At Asiacrypt 2007, Vaudenay studied security and privacy models for these protocols. We extend this model to protocols which offer reader authentication to tags. Whenever corruption i ...

About Machine-Readable Travel Documents

Serge Vaudenay, Martin Vuagnoux, Jean Monnerat

Passports are now equipped with RFID chips that contain private information, biometric data, and a digital signature by issuing authorities. We review most of applicable security and privacy issues. We argue that the main privacy issue is not unauthorized ...

Architecture for Secure and Private Vehicular Communications

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

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 ...

Mix-Zones for Location Privacy in Vehicular Networks

Jean-Pierre Hubaux, Panagiotis Papadimitratos, Mark Felegyhazi, Julien Freudiger, 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 ...

On Privacy Models for RFID

Serge Vaudenay

We provide a formal model for identification schemes. Under this model, we give strong definitions for security and privacy. Our model captures the notion of a powerful adversary who can monitor all communications, trace tags within a limited period of tim ...

RFID Privacy based on Public-Key Cryptography (Abstract)

Serge Vaudenay

RFID systems makes it possible for a server to identify known tags in wireless settings. As they become more and more pervasive, people privacy is more and more threatened. In this talk, we list a few models for privacy in RFID and compare them. We review ...

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 ...
