Protecting and Evaluating Genomic Privacy in Medical Tests and Personalized Medicine

Jean-Pierre Hubaux, Jacques Rougemont, Erman Ayday, Jean Louis Raisaro

In this paper, we propose privacy-enhancing technologies for medical tests and personalized medicine methods that use patients' genomic data. Focusing on genetic disease-susceptibility tests, we develop a new architecture (between the patient and the medic ...

Bimetallic Oxidative Addition Involving Radical Intermediates in Nickel-Catalyzed Alkyl-Alkyl Kumada Coupling Reactions

Xile Hu, Matthew Wodrich, Jan Breitenfeld, Jesus Ruiz

Many nickel-based catalysts have been reported for cross-coupling reactions of nonactivated alkyl halides. The mechanistic understanding of these reactions is still primitive. Here we report a mechanistic study of alkyl-alkyl Kumada coupling catalyzed by a ...

Ron was wrong, Whit is right

Arjen Lenstra, Joppe Willem Bos, Thorsten Kleinjung, Maxime Augier, Christophe Wachter

We performed a sanity check of public keys collected on the web. Our main goal was to test the validity of the assumption that different random choices are made each time keys are generated. We found that the vast majority of public keys work as intended. ...

Scalable and Secure Polling in Dynamic Distributed Networks

Rachid Guerraoui, Anne-Marie Kermarrec, Hamza Harkous, Florian Huc

We consider the problem of securely conducting a poll in synchronous dynamic networks equipped with a Public Key Infrastructure (PKI). Whereas previous distributed solutions had a communication cost of O(n^2) in an n nodes system, we present SPP (Secure an ...

Deniable RSA Signature: The Raise and Fall of Ali Baba

Serge Vaudenay

The 40 thieves realize that the fortune in their cave is vanishing. A rumor says that Ali Baba has been granted access (in the form of a certificate) to the cave but they need evidence to get justice from the Caliph. On the other hand, Ali Baba wants to be ...

Cryptanalysis of the Double-Moduli Cryptosystem

Serge Vaudenay, Sonia Mihaela Bogos

In this article we present a lattice attack done on a NTRU-like scheme introduced by Verkhovsky in [1]. We show how, based on the relation between the public and private key, we can construct an attack which allows any passive adversary to decrypt the encr ...

Imp2 controls oxidative phosphorylation and is crucial for preserving glioblastoma cancer stem cells

Johan Auwerx, Richardus Houtkooper, Ivan Stamenkovic, Michalina Janiszewska

Growth of numerous cancer types is believed to be driven by a subpopulation of poorly differentiated cells, often referred to as cancer stem cells (CSCs), that have the capacity for self-renewal, tumor initiation, and generation of nontumorigenic progeny. ...

On the Cryptanalysis of Public-Key Cryptography

Joppe Willem Bos

Nowadays, the most popular public-key cryptosystems are based on either the integer factorization or the discrete logarithm problem. The feasibility of solving these mathematical problems in practice is studied and techniques are presented to speed-up the ...

Privacy-Enhancing Technologies for Medical Tests Using Genomic Data

Jean-Pierre Hubaux, Erman Ayday, Jean Louis Raisaro

In this paper, we propose privacy-enhancing technologies for medical tests and personalized medicine methods, which utilize patients' genomic data. First, we highlight the potential privacy threats on genomic data and the challenges of providing privacy-pr ...

OREN: Optimal Revocations in Ephemeral Networks

Jean-Pierre Hubaux, Maxime Raya, Igor Bilogrevic

Public-key certificates allow a multitude of entities to securely exchange and verify the authenticity of data. However, the ability to effectively revoke compromised or untrustworthy certificates is of great importance when coping with misbehavior. In thi ...
