Improved Cryptanalysis of Skein

Willi Meier, Onur Özen, Jean-Philippe Aumasson

The hash function Skein is the submission of Ferguson et al. to the NIST Hash Competition, and is arguably a serious candidate for selection as SHA-3. This paper presents the first third-party analysis of Skein, with an extensive study of its main componen ...

Evaluating Resistance of MCML Technology to Power Analysis Attacks Using a Simulation-Based Methodology

Paolo Ienne, Francesco Regazzoni, Yusuf Leblebici, Zeynep Toprak Deniz

This paper explores the resistance of MOS Current Mode Logic (MCML) against attacks based on the observation of the power consumption. Circuits implemented in MCML, in fact, have unique characteristics both in terms of power consumption and the dependency ...

Differential influence of hands posture on mental rotation of hands and feet in left and right handers

Olaf Blanke, Silvio Ionta

The representation of the body in the brain is continuously updated with regard to peripheral factors such as position or movement of body parts. In the present study, we investigated the effects of arm posture on the mental rotation of hands and feet. Six ...

On the naturality of the exterior differential

Marc Troyanov

We give sufficient conditions for the naturallity of the exterior differential under Sobolev mappings. In other words we study the validity of the equation

d\, f^* \alpha = f^*\; d\alpha

for a smooth form

\alpha

and a Sobolev map

Differential neuroglycan C expression during retinal degeneration in Rpe65(-/-) mice

Pascal Escher

Purpose: An increased mRNA expression of the genes coding for the extracellular matrix proteins neuroglycan C (NGC), interphotoreceptor matrix proteoglycan 2 (IMPG2), and CD44 antigen (CD44) has been observed during retinal degeneration in mice with a targ ...
