The 2nd Competition on Counter Measures to 2D Face Spoofing Attacks

Sébastien Marcel, André Anjos, Ivana Chingovska

As a crucial security problem, anti-spoofing in biometrics, and particularly for the face modality, has achieved great progress in the recent years. Still, new threats arrive in form of better, more realistic and more sophisticated spoofing attacks. The ob ...

On Selecting the Nonce Length in Distance-Bounding Protocols

Serge Vaudenay, Christos Dimitrakakis, Aikaterini Mitrokotsa

Distance-bounding protocols form a family of challenge-response authentication protocols that have been introduced to thwart relay attacks. They enable a verifier to authenticate and to establish an upper bound on the physical distance to an untrusted prov ...

Complementary Countermeasures for Detecting Scenic Face Spoofing Attacks

Sébastien Marcel, André Anjos

The face recognition community has finally started paying more attention to the long-neglected problem of spoofing attacks. The number of countermeasures is gradually increasing and fairly good results have been reported on the publicly available databases ...

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 ...

Security and Privacy in RFID Systems

Khaled Ouafi

This PhD thesis is concerned with authentication protocols using portable lightweight devices such as RFID tags. these devices have lately gained a significant attention for the diversity of the applications that could benefit form their features, ranging ...

Statistical and Algebraic Cryptanalysis of Lightweight and Ultra-Lightweight Symmetric Primitives

Pouyan Sepehrdad

Symmetric cryptographic primitives such as block and stream ciphers are the building blocks in many cryptographic protocols. Having such blocks which provide provable security against various types of attacks is often hard. On the other hand, if possible, ...

On the Pseudorandom Function Assumption in (Secure) Distance-Bounding Protocols

Serge Vaudenay, Aikaterini Mitrokotsa

In this paper, we show that many formal and informal security results on distance-bounding (DB) protocols are incorrect/incomplete. We identify that this inadequacy stems from the fact that the pseudorandom function (PRF) assumption alone, invoked in many ...

Fast Key Recovery Attack on ARMADILLO1 and Variants

Serge Vaudenay, Pouyan Sepehrdad, Petr Susil

The ARMADILLO cryptographic primitive is a multi-purpose cryptographic primitive for RFID devices proposed at CHES’10. The main purpose of the primitive is to provide a secure authentication in a challenge-response protocol. It has two versions, named ARMA ...

Counter-Measures to Photo Attacks in Face Recognition: a public database and a baseline

Sébastien Marcel, André Anjos

A common technique to by-pass 2-D face recognition systems is to use photographs of spoofed identities. Unfortunately, research in counter-measures to this type of attack have not kept-up - even if such threats have been known for nearly a decade, there se ...
