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 ...
Recent developments in information and communication technologies have been profound and life-changing. Most people are now equipped with smart phones with high computation power and communication capabilities. These devices can efficiently run multiple so ...
The creation of wide-area, real-time monitoring systems for the road network has the potential to achieve a step change in both our understanding of the evolution of congestion and forecasting/information to minimise its economic consequences. While such c ...
he Vaudenay model for RFID privacy from Asiacrypt 2007 suffers from the impossibility to address strong privacy. It has however been shown by Ng et al. at ESORICS 2008 that the impossibility result leads to no practical threat, so that the definition from ...
Modern mobile devices are fast, programmable and feature localization and wireless capabilities. These technological advances notably facilitate mobile access to Internet, development of mobile applications and sharing of personal information, such as loca ...
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 ...
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 ...
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 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 ...
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 ...
