The Extended Access Control for Machine Readable Travel Documents

Serge Vaudenay, Rafik Chaabouni

Machine Readable travel documents have been rapidly put in place since 2004. The initial standard was made by the ICAO and it has been quickly followed by the Extended Access Control (EAC). In this paper we discuss about the evolution of these standards an ...

Mutual Authentication in RFID: Security and Privacy

Serge Vaudenay, Radu-Ioan Paise

In RFID protocols, tags identify and authenticate themselves to readers. At Asiacrypt 2007, Vaudenay studied security and privacy models for these protocols. We extend this model to protocols which offer reader authentication to tags. Whenever corruption i ...

The Complexity of Distinguishing Distributions

Serge Vaudenay, Thomas Baignères

Cryptography often meets the problem of distinguishing distributions. In this paper we review techniques from hypothesis testing to express the advantage of the best distinguisher limited to a given number of samples. We link it with the Chernoff informati ...

On the Security of HB# against a Man-in-the-Middle Attack

Serge Vaudenay, Khaled Ouafi

At EuroCrypt ’08, Gilbert, Robshaw and Seurin proposed HB# to improve on HB+ in terms of transmission cost and security against man-in-the-middle attacks. Although the security of HB# is formally proven against a certain class of man- in-the-middle adversa ...

Hash-and-Sign with Weak Hashing Made Secure

Serge Vaudenay, Sylvain Pasini

Digital signatures are often proven to be secure in the random oracle model while hash functions deviate more and more from this idealization. Liskov proposed to model a weak hash function by a random oracle together with another oracle allowing to break s ...

Linear Cryptanalysis of Non Binary Ciphers (with an application to SAFER)

Serge Vaudenay, Thomas Baignères, Jacques Stern

In this paper we re-visit distinguishing attacks. We show how to generalize the notion of linear distinguisher to arbitrary sets. Our thesis is that our generalization is the most natural one. We compare it with the one by Granboulan et al. from FSE'06 by ...

About Machine-Readable Travel Documents

Serge Vaudenay, Martin Vuagnoux

Passports are documents that help immigration officers to identify people. In order to strongly authenticate their data and to automatically identify people, they are now equipped with RFID chips. These contain private information, biometrics, and a digita ...

TCHo: a Hardware-Oriented Trapdoor Cipher

Serge Vaudenay, Willi Meier, Jean-Philippe Aumasson

This paper improves the Finiasz-Vaudenay construction of TCHo, a hardware-oriented public-key cryptosystem, whose security relies in the hardness of finding a low-weight multiple of a given polynomial, and on the decoding of certain noisy cyclic linear cod ...
