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.

Using Face Morphing to Protect Privacy

Touradj Ebrahimi

The widespread use of digital video surveillance systems has also increased the concerns for violation of privacy rights. Since video surveillance systems are invasive, it is a challenge to find an acceptable balance between privacy of the public under sur ...

On Modeling Terrorist Frauds

Serge Vaudenay

Quite recently, distance-bounding protocols received a lot of attention as they offer a good solution to thwart relay attacks. Their security models at still unstable, especially when considering terrorist fraud. This considers the case where a malicious p ...

The Bussard-Bagga and Other Distance-Bounding Protocols under Attacks

Serge Vaudenay, Aikaterini Mitrokotsa, Asli Bay, Iosif-Daniel Spulber

The communication between an honest prover and an honest verifier can be intercepted by a malicious man-in-the-middle (MiM), without the legitimate interlocutors noticing the intrusion. The attacker can simply relay messages from one party to another, even ...

The Inconvenient Truth about Web Certificates

Jean-Pierre Hubaux, Julien Freudiger, Nevena Vratonjic, Vincent Bindschaedler

HTTPS is the de facto standard for securing Internet communications. Although it is widely deployed, the security provided with HTTPS in practice is dubious. HTTPS may fail to provide security for multiple reasons, mostly due to certificate-based authentic ...

On the Static Diffie-Hellman Problem on Elliptic Curves over Extension Fields

Robert Granger

We show that for any elliptic curve

E(\mathbb{F}_{q^n})

, if an adversary has access to a Static Diffie-Hellman Problem (Static DHP) oracle, then by making

O(q^{1-\frac{1}{n+1}})

Static DHP oracle queries during an initial learning phase, for fixed $n>1 ...

Secure and Privacy-Enhancing Vehicular Communication Demonstration of Implementation and Operation

Panagiotis Papadimitratos, Petra Ardelean

With a number of projects developing vehicular communication systems, there is rising awareness on threats and the need to introduce security and privacy-enhancing mechanisms. With recent results, in principle in agreement across different major projects, ...

Impact of Vehicular Communications Security on Transportation Safety

Jean-Pierre Hubaux, Panagiotis Papadimitratos

Transportation safety, one of the main driving forces of the development of vehicular communication (VC) systems, relies on high-rate safety messaging (beaconing). At the same time, there is consensus among authorities, industry, and academia on the need t ...

Theory and tool support for the formal verification of cryptographic protocols

Sébastien Briais

Cryptographic protocols are an essential component of network communications. Despite their relatively small size compared to other distributed algorithms, they are known to be error-prone. This is due to the obligation to behave robustly in the context of ...

Security-Preserving Asymmetric Protocol Encapsulation

Serge Vaudenay

Query-response based protocols between a client and a server such as SSL, TLS, SSH are asymmetric in the sense that the querying client and the responding server play different roles, and for which there is a need for two-way linkability between queries an ...

Stratégies aéroportuaires en Suisse

Tristan Chevroulet, Aymeric Sevestre

Airport operation in Switzerland is confided to companies with private law status. The Federal Ministry has drawn up a sectoral Plan of air infrastructure, which is an instrument both of regional policy and of planning. It does not create new rights but fi ...
