Hardware Attacks against Hash-based Cryptographic Algorithms

Aymeric Genet

This thesis surveys the current state of the art of hash-based cryptography with a view to finding vulnerabilities related to side-channel attacks and fault attacks. For side-channel investigation, we analyzed the power consumption of an Arduino Due microc ...

Indiscreet discrete logarithms

Robert Granger

In 2013 and 2014 a revolution took place in the understanding of the discrete logarithm problem (DLP) in finite fields of small characteristic. Consequently, many cryptosystems based on cryptographic pairings were rendered completely insecure, which serves ...

Computational aspects of correlation power analysis

Joppe Willem Bos, Paul Bottinelli

Since the discovery of simple power attacks, the cryptographic research community has developed significantly more advanced attack methods. The idea behind most algorithms remains to perform a statistical analysis by correlating the power trace obtained wh ...

Some Cryptanalytic Results on Lizard

Subhadeep Banik

Lizard is a lightweight stream cipher proposed by Hamann, Krause and Meier in IACR ToSC 2017. It has a Grain-like structure with two state registers of size 90 and 31 bits. The cipher uses a 120 bit secret key and a 64 bit IV. The authors claim that Lizard ...

Nanomechanics of multidomain neuronal cell adhesion protein contactin revealed by single molecule AFM and SMD

Giovanni Dietler, Andrzej Kulik, Karolina Anna Mikulska Ruminska

Contactin-4 (CNTN4) is a complex cell adhesion molecule (CAM) localized at neuronal membranes, playing a key role in maintaining the mechanical integrity and signaling properties of the synapse. CNTN4 consists of six immunoglobulin C2 type (IgC2) domains a ...

DES S-box generator

Serge Vaudenay, Lauren De Meyer

The Data Encryption Standard (DES) is a cryptographic algorithm, designed by IBM, that was selected to be the national standard in 1977 by the National Bureau of Standards. The algorithm itself was entirely published but the design criteria were kept secre ...

Instruction Set Extensions for Secure Applications

Paolo Ienne, Francesco Regazzoni

The main goal of this paper is to expose the community to past achievements and future possible uses of Instruction Set Extension (ISE) in security applications. Processor customization has proven to be an effective way for achieving high performance with ...

Signature Schemes Secure Against Hard-to-Invert Leakage

Sebastian Faust

Side-channel attacks allow the adversary to gain partial knowledge of the secret key when cryptographic protocols are implemented in real-world hardware. The goal of leakage resilient cryptography is to design cryptosystems that withstand such attacks. In ...

Microarchitectural Low-Power Design Techniques for Embedded Microprocessors

Jeremy Hugues-Felix Constantin

With the omnipresence of embedded processing in all forms of electronics today, there is a strong trend towards wireless, battery-powered, portable embedded systems which have to operate under stringent energy constraints. Consequently, low power consumpti ...

Clever Arbiters Versus Malicious Adversaries

Serge Vaudenay

When moving from known-input security to chosen-input security, some generic attacks sometimes become possible and must be discarded by a specific set of rules in the threat model. Similarly, common practices consist of fixing security systems, once an exp ...
