Privacy-Preserving Multi-agent Constraint Satisfaction

Boi Faltings, Thomas Léauté

Constraint satisfaction has been a very successful paradigm for solving problems such as resource allocation and planning. Many of these problems pose themselves in a context involving multiple agents, and protecting privacy of information among them is of ...

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 ...

Traceable Privacy of Recent Provably-Secure RFID Protocols

Khaled Ouafi

One of the main challenges in RFIDs is the design of privacy-preserving authentication protocols. Indeed, such protocols should not only allow legitimate readers to authenticate tags but also protect these latter from privacy-violating attacks, ensuring th ...

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 ...

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 ...

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 ...

RFID Traceability: A Multilayer Problem

Gildas Avoine, Philippe Oechslin

RFID tags have very promising applications in many domains (retail, rental, surveillance, medicine to name a few). Unfortunately the use of these tags can have serious implications on the privacy of people carrying tagged items. Serious opposition from con ...

A Scalable and Provably Secure Hash-Based RFID Protocol

Gildas Avoine, Philippe Oechslin

The biggest challenge for RFID technology is to provide benefits without threatening the privacy of consumers. Many solutions have been suggested but almost as many ways have been found to break them. An approach by Ohkubo, Suzuki and Kinoshita using an in ...

Vehicle tracking using acoustic and video sensors

Volkan Cevher

In target tracking, fusing multi-modal sensor data under a power-performance trade-off is becoming increasingly important. Proper fusion of multiple modalities can help in achieving better tracking performance while decreasing the total power consumption. ...
