The Bussard-Bagga and Other Distance-Bounding Protocols under Attacks

Serge Vaudenay, Aikaterini Mitrokotsa, Asli Bay, Iosif-Daniel Spulber

The communication between an honest prover and an honest verifier can be intercepted by a malicious man-in-the-middle (MiM), without the legitimate interlocutors noticing the intrusion. The attacker can simply relay messages from one party to another, even ...

Cryptographic Hash Functions in Groups and Provable Properties

Juraj Sarinay

We consider several "provably secure" hash functions that compute simple sums in a well chosen group (G,*). Security properties of such functions provably translate in a natural way to computational problems in G that are simple to define and possibly also ...

Distance Bounding with IEEE 802.15.4a: Attacks and Countermeasures

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

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 ...

Contextual grouping: discovering real-life interaction types from longitudinal Bluetooth data

Daniel Gatica-Perez

By exploiting built-in sensors, mobile smartphone have become attractive options for large-scale sensing of human behavior as well as social interaction. In this paper, we present a new probabilistic model to analyze longitudinal dynamic social networks cr ...

Scalable and Secure Aggregation in Distributed Networks

Rachid Guerraoui, Anne-Marie Kermarrec, Hamza Harkous, Florian Huc

We consider the problem of computing an aggregation function in a \emph{secure} and \emph{scalable} way. Whereas previous distributed solutions with similar security guarantees have a communication cost of

O(n^3)

, we present a distributed protocol that r ...

Effectiveness of Distance-Decreasing Attacks Against Impulse Radio Ranging

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

We expose the vulnerability of an emerging wireless ranging technology, impulse radio ultra-wide band (IR-UWB), to distance-decreasing attacks on the physical communication layer (PHY). These attacks violate the security of secure ranging protocols that al ...

Characterization of the secrecy region of a single relay cooperative system

Ninoslav Marina

Security is an important aspect for the future wire- less networks. Since the number of network nodes increases con- stantly, and, in addition, the networks are decentralized and ad- hoc in nature, it becomes more challenging to apply the current cryptogra ...

Anonymous roaming in universal mobile telecommunication system mobile networks

Mitra Fatemi

A secure roaming protocol for mobile networks is proposed. Roaming has been analysed in some schemes from the security point of view; however, there are vulnerabilities in most of them and so the claimed security level is not achieved. The scheme offered b ...
