Security of Full-State Keyed Sponge and Duplex: Applications to Authenticated Encryption

Damian Vizár, Reza Reyhanitabar

We provide a security analysis for full-state keyed Sponge and full-state Duplex constructions. Our results can be used for making a large class of Sponge-based authenticated encryption schemes more efficient by concurrent absorption of associated data and ...

Misuse-Resistant Variants of the OMD Authenticated Encryption Mode

Serge Vaudenay, Damian Vizár, Reza Reyhanitabar

We present two variants of OMD which are robust against nonce misuse. Security of OMD---a CAESAR candidate---relies on the assumption that implementations always ensure correct use of nonce (a.k.a. message number); namely that, the nonce never gets repeate ...

Automated Side-Channel Vulnerability Discovery and Hardening

Ali Galip Bayrak

In traditional cryptography, an attacker tries to infer a mathematical relationship between the inputs and outputs of a cryptosystem to recover secret information. With the advances in the theoretical basis of the cryptographic algorithms, this task became ...

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 ...

HELEN: A Public-Key Cryptosystem Based on the LPN and the Decisional Minimal Distance Problems

Serge Vaudenay, Alexandre Raphaël Duc

We propose HELEN, a code-based public-key cryptosystem whose security is based on the hardness of the Learning from Parity with Noise problem (LPN) and the decisional minimum distance problem. We show that the resulting cryptosystem achieves indistinguisha ...

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 ...

HELEN: a Public-key Cryptosystem Based on the LPN Problem (Extended Abstract)

Serge Vaudenay, Alexandre Raphaël Duc

We propose HELEN, a new code-based public-key cryptosystem whose security is based on the hardness of the Learning from Parity with Noise problem~(LPN) and the decisional minimum distance problem. We show that the resulting cryptosystem achieves indistingu ...
