Relay attacks (and, more generally, man-in-the-middle attacks) are a serious threat against many access control and payment schemes. In this work, we present distance-bounding protocols, how these can deter relay attacks, and the security models formalizin ...

Secure & Lightweight Distance-Bounding

Serge Vaudenay, Aikaterini Mitrokotsa

Distance-bounding is a practical solution to be used in security-sensitive contexts, mainly to prevent relay attacks. The main challenge when designing such protocols is maintaining their inexpensive cryptographic nature, whilst being able to protect again ...

Practical & Provably Secure Distance-Bounding

Serge Vaudenay, Aikaterini Mitrokotsa

From contactless payments to remote car unlocking, many applications are vulnerable to relay attacks. Distance bounding protocols are the main practical countermeasure against these attacks. At FSE 2013, we presented SKI as the first family of provably sec ...

Smashing WEP in A Passive Attack

Serge Vaudenay, Martin Vuagnoux, Pouyan Sepehrdad, Petr Susil

In this paper, we report extremely fast and optimised active and passive attacks against the old IEEE 802.11 wireless communication protocol WEP. This was achieved through a huge amount of theoretical and experimental analysis (capturing WiFi packets), ref ...

LBP-TOP based countermeasure against face spoofing attacks

Sébastien Marcel, André Anjos, Tiago De Freitas Pereira

User authentication is an important step to protect information and in this eld face biometrics is advantageous. Face biometrics is natural, easy to use and less human-invasive. Unfortunately, recent work has revealed that face biometrics is vulnerable to ...

Competition on Counter Measures to 2-D Facial Spoofing Attacks

Sébastien Marcel, André Anjos, Murali Mohan Chakka, Zhiwei Zhang

Spoofing identities using photographs is one of the most common techniques to attack 2-D face recognition systems. There seems to exist no comparative studies of different techniques using the same protocols and data. The motivation behind this competition ...

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 ...

Evaluating Resistance of MCML Technology to Power Analysis Attacks Using a Simulation-Based Methodology

Paolo Ienne, Francesco Regazzoni, Yusuf Leblebici, Zeynep Toprak Deniz

This paper explores the resistance of MOS Current Mode Logic (MCML) against attacks based on the observation of the power consumption. Circuits implemented in MCML, in fact, have unique characteristics both in terms of power consumption and the dependency ...
