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 ...

Distance Bounding with IEEE 802.15.4a: Attacks and Countermeasures

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

Impulse Radio Ultra-Wideband, in particular the recent standard IEEE 802.15.4a, is a primary candidate for implementing distance bounding protocols, thanks to its ability to perform accurate indoor ranging. Distance bounding protocols allow two wireless de ...

A Note on a Privacy-Preserving Distance-Bounding Protocol

Aikaterini Mitrokotsa, Jean-Philippe Aumasson

Distance bounding protocols enable a device to establish an upper bound on the physical distance to a communication partner so as to prevent location spoofing, as exploited by relay attacks. Recently, Rasmussen and Cˇapkun (ACM-CCS’08) observed that these ...

Short Undeniable Signatures Based on Group Homomorphisms

Serge Vaudenay, Jean Monnerat

This paper is devoted to the design and analysis of short undeniable signatures based on a random oracle. Exploiting their online property, we can achieve signatures with a fully scalable size depending on the security level. To this end, we develop a gene ...
