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.

Contactless access control systems are critical for security but often vulnerable to relay attacks. In this paper, we define an integrated security and privacy model for access control using distance bounding (DB) which is the most robust solution to preve ...

VNToR: Network Virtualization at the Top-of-Rack Switch

Edouard Bugnion, Georgios Ioannidis, Sam David Whitlock, Jonas Fietz

Cloud providers typically implement abstractions for net- work virtualization on the server, within the operating sys- tem that hosts the tenant virtual machines or containers. Despite being flexible and convenient, this approach has funda- mental problems ...

Privacy-Preserving Photo Sharing based on a Public Key Infrastructure

Touradj Ebrahimi, Lin Yuan, David Mc Nally

A significant number of pictures are posted to social media sites or exchanged through instant messaging and cloud-based sharing services. Most social media services offer a range of access control mechanisms to protect users privacy. As it is not in the b ...

DISTINGUISHING “CROWDED” ORGANIZATIONS FROM GROUPS AND COMMUNITIES: IS THREE A CROWD?

Christopher Tucci, Gianluigi Viscusi

In conventional wisdom on crowdsourcing, the number of people define the crowd and maximizing this number is often assumed to be the goal of any crowdsourcing exercise. However, we propose that there are structural characteristics of the crowd that might b ...

Electrically conductive self-healing polymer composite coatings

Véronique Michaud, Yves Leterrier, Brennan Margaret Bailey

The goal of the research described herein is the fabrication and assessment of electrically conductive partially-cured epoxy coatings which, upon cracking, autonomously restore barrier, mechanical and electrical properties via a microcapsule based healing ...

TOA: a tag-owner-assisting RFID authentication protocol toward access control and ownership transfer

Chen Zhang, Chao Wang, Qiang Wang, Lei Xie

This paper addresses radio frequency identification (RFID) authentication and ownership transfer in offline scenarios. Four typical related works are reviewed in detail. A series of shortcomings and vulnerabilities of them are pointed out. A new RFID authe ...

Wiley-Blackwell2014

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 ...
