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.

Security and Privacy in RFID Systems

Khaled Ouafi

This PhD thesis is concerned with authentication protocols using portable lightweight devices such as RFID tags. these devices have lately gained a significant attention for the diversity of the applications that could benefit form their features, ranging ...

Strong Privacy for RFID Systems from Plaintext-Aware Encryption

Serge Vaudenay, Khaled Ouafi

he Vaudenay model for RFID privacy from Asiacrypt 2007 suffers from the impossibility to address strong privacy. It has however been shown by Ng et al. at ESORICS 2008 that the impossibility result leads to no practical threat, so that the definition from ...

Approximation for Problems in Multi-User Information Theory

Soheil Mohajerzefreh

The main goal in network information theory is to identify fundamental limits of communication over networks, and design solutions which perform close to such limits. After several decades of effort, many important problems still do not have a characteriza ...

Provable Security in Cryptography

Thomas Baignères

These lecture notes are a compilation of some of my readings while I was preparing two lectures given at EPFL on provable security in cryptography. They are essentially based on a book chapter from David Pointcheval called “Provable Security for Public Key ...

Cryptography based on error correcting codes

Lorenz Minder

The idea to use error-correcting codes in order to construct public key cryptosystems was published in 1978 by McEliece [ME1978]. In his original construction, McEliece used Goppa codes, but various later publications suggested the use of different familie ...

Decorrelation over Infinite Domains: the Encrypted CBC-MAC Case

Serge Vaudenay

Decorrelation theory has recently been proposed in order to address the security of block ciphers and other cryptographic primitives over a finite domain. We show here how to extend it to infinite domains, which can be used in the Message Authentication Co ...

Comparison of the Randomness Provided by Some AES Candidates

Serge Vaudenay

Using the decorrelation techniques we compare the randomness of three schemes used in the AES candidates. The target schemes are the original Feistel scheme and two modified Feistel schemes: the MARS-like structure and the CAST256-like structure. As a resu ...
