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.

JAGR: an autonomous self-recovering application server

George Candea

This paper demonstrates that the dependability of generic, evolving J2EE applications can be enhanced through a combination of a few recovery-oriented techniques. Our goal is to reduce downtime by automatically and efficiently recovering from a broad class ...

Beyond "Web of Trust": Enabling P2P E-commerce

Karl Aberer, Manfred Hauswirth, Anwitaman Datta

The huge success of eBay has proven the demand for customer-to-customer (C2C) electronic commerce. eBay is a centralized infrastructure with all its scalability problems (network bandwidth, server load, availability, etc.). In this paper we argue that C2C ...

An authentication scheme based on roots of sparse polynomials

Mohammad Amin Shokrollahi

We describe an authentication scheme whose security is based on the hardness of finding roots of systems of sparse polynomial equations in many variables and of high degree. One of the new ideas is the use of many keys. In one authentication session, a sma ...

BISS: Building Secure Routing out of an Incomplete Set of Security Associations

Jean-Pierre Hubaux, Srdan Capkun

We investigate secure routing in ad hoc networks in which security associations exist only between a subset of all pairs of nodes. We focus on source routing protocols. We show that to establish secure routes, it is in general not necessary that security a ...

Small Worlds in Security Systems: an Analysis of the PGP Certificate Graph

Jean-Pierre Hubaux, Levente Buttyan, Srdan Capkun

We propose a new approach to securing computer networks. With this approach, we achieve security in a fully self-organized manner; by this we mean that to secure a computer network, a security system does not require any kind of certification authority or ...
