Graph Chatbot

Chattez avec Graph Search

Posez n’importe quelle question sur les cours, conférences, exercices, recherches, actualités, etc. de l’EPFL ou essayez les exemples de questions ci-dessous.

AVERTISSEMENT : Le chatbot Graph n'est pas programmé pour fournir des réponses explicites ou catégoriques à vos questions. Il transforme plutôt vos questions en demandes API qui sont distribuées aux différents services informatiques officiellement administrés par l'EPFL. Son but est uniquement de collecter et de recommander des références pertinentes à des contenus que vous pouvez explorer pour vous aider à répondre à vos questions.

User-Aided Data Authentication

Sylvain Pasini

All classical authentication protocols are based on pre-shared authentic information such as long-term secret keys or a public key infrastructure. However, there are many practical settings, where participants can additionally employ authentic Out-Of-Band ...

Improved Cryptanalysis of Skein

Willi Meier, Onur Özen, Jean-Philippe Aumasson

The hash function Skein is the submission of Ferguson et al. to the NIST Hash Competition, and is arguably a serious candidate for selection as SHA-3. This paper presents the first third-party analysis of Skein, with an extensive study of its main componen ...

Enabling Privacy For Distributed Video Coding by Transform Domain Scrambling

Touradj Ebrahimi, Frédéric Dufaux, Mourad Ouaret

In this paper, a novel scheme for video scrambling is introduced for Distributed Video Coding. The goal is to conceal video information in several applications such as video surveillance and anonymous video communications to preserve privacy. This is achie ...

Improved Side Information Generation with Iterative Decoding and Frame Interpolation for Distributed Video Coding

Touradj Ebrahimi, Frédéric Dufaux, Mourad Ouaret

Distributed Video Coding (DVC) is a new paradigm in video coding, which is receiving a lot of interests nowadays. Side Information (SI) generation is a key function in the DVC decoder, and plays a key-role in determining the performance of the codec. This ...

Novel front-end circuit architectures for integrated bio-electronic interfaces

Alexandre Schmid, Carlotta Guiducci, Yusuf Leblebici

The prospective use of upcoming nanometer CMOS technology nodes (65nm, 45nm, and beyond) in bio-electronic interfaces is raising a number of important issues concerning circuit architectures and design. In particular, the advantages of scaling and higher d ...

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 ...

Fibroblastic reticular cells in lymph nodes regulate the homeostasis of naive T cells

Boris Hinz

Interleukin 7 is essential for the survival of naive T lymphocytes. Despite its importance, its cellular source in the periphery remains poorly defined. Here we report a critical function for lymph node access in T cell homeostasis and identify T zone fibr ...

Passive-Only Key Recovery Attacks on RC4

Serge Vaudenay, Martin Vuagnoux

We present several weaknesses in the key scheduling algorithm of RC4 when the secret key contains an initialization vector - a cryptographic scheme typically used by the WEP and WPA protocols to protect IEEE 802.11 wireless communications. First, we show h ...

Noisy Tags: A Pretty Good Key Exchange Protocol for RFID Tags

Gildas Avoine

We propose a protocol that can be used between an RFID tag and a reader to exchange a secret without performing any expensive computation. Similarly to the famous blocker tag suggested by Juels, Rivest, and Szydlo, our scheme makes use of special tags that ...

Fraud within Asymmetric Multi-Hop Cellular Networks

Gildas Avoine

At Financial Cryptography 2003, Jakobsson, Hubaux, and Buttyan suggested a lightweight micro-payment scheme aimed at encouraging routing collaboration in asymmetric multi-hop cellular networks. We will show in this paper that this scheme suffers from some ...
