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.

Input-Aware Equivocable Commitments and UC-secure Commitments With Atomic Exchanges

Serge Vaudenay

We define a new primitive, input-aware equivocable commitment, baring similar hardness assumptions as plaintext-aware encryption and featuring equivocability. We construct an actual input-aware equivocable commitment protocol, based on a flavor of Diffie-H ...

Low cost security for sensor networks

Christina Fragouli, Lorenzo Keller, Iris Safaka, Emre Atsan

We design and evaluate a lightweight encryption protocol suitable for sensor networks, that enables weak security in the presence of passive eavesdroppers. At every communication round, our protocol creates a key between each sensor node and the sink, by a ...

Laboratory and in Situ Simulation Tests of the Fracturing in the EDZ around Galleries in Opalinus Clay

Vincent Labiouse

Within the framework of the TIMODAZ project laboratory and in-situ experiments have been performed to study the failure processes around tunnels in laminated clay rich sedimentary rocks at reduced scale. The fracture patterns observed in the hollow cylinde ...

Joint Identity-Message Coding for Sensor Networks

Christina Fragouli, Suhas Diggavi, Lorenzo Keller, Mahdi Jafari Siavoshani

In a significant class of sensor-network applications, the identities of the reporting sensors constitute the bulk of the communicated data, whereas the message itself can be as small as a single bit—for instance, in many cases, sensors are used to detect ...

Explaining thermal failure in saturated clays

Lyesse Laloui, Bertrand François

Failure conditions in soils at elevated temperatures appear to be strongly dependent on the history of the application of stress and temperature. Four cases of such history leading to various modes of failure are identified and interpreted in terms of Ther ...

Failure in multiphase geomaterias

Lyesse Laloui

The contributions assembled in the present volume proceed from the lectures of the 2009 ALERT Geomaterials School devoted to the Failure in the multiphase geomaterials. The multiphase behaviour of geomaterials used to be mainly considered from the point of ...

A New Message Recognition Protocol with Self-recoverability for Ad Hoc Pervasive Networks

Atefeh Mashatan

We examine the problem of message recognition by reviewing the definitions and the security model in the literature. In particular, we examine the Jane Doe protocol, which was proposed by Lucks et al., more closely and note its inability to recover in case ...

SenseCode: Network Coding for Reliable Sensor Networks

Christina Fragouli, Lorenzo Keller, Emre Atsan

Designing a communication protocol for sensor networks often involves obtaining the "right" trade-off between energy efficiency and reliability. In this paper, we show that network coding provides a means to elegantly balance these two goals. We present th ...

A Study of Forward Error Correction Schemes for Reliable Transport in Underwater Sensor Networks

Florent Frédéric Garcin

Underwater communications is a very challenging topic due to its singular channel characteristics. Most protocols used in terrestrial wireless communications can not be directly applied in the underwater world. A high bit error rate and low propagation del ...

Game Theoretic Modeling of Malicious Users in Collaborative Networks

Georgios Theodorakopoulos

If a network is to operate successfully, its users need to collaborate. Collaboration takes the form of following a network protocol and involves some resource expenditure on the part of the user. Therefore, users cannot automatically be expected to follow ...
