First-principles molecular dynamics simulations of proton diffusion in cubic BaZrO3 perovskite under strain conditions

First-principles molecular dynamics simulations have been employed to analyse the proton diffusion in cubic BaZrO3 perovskite at 1300 K. A non-linear effect on the proton diffusion coefficient arising from an applied isometric strain up to 2 % of the latti ...

Non-centrosymmetric plasmonic crystals for second-harmonic generation with controlled anisotropy and enhancement

Elyahou Kapon, Benjamin Dwir, Justyna Szeszko

Rectangular arrays of pyramidal recesses coated by silver film are investigated by means of polarization-resolved nonlinear microscopy at 900 nm fundamental wavelength, demonstrating strong dependence of the dipole-allowed SHG upon the lattice parameters. ...

Asymmetric structure of 90 deg. domain walls and interactions with defects in PbTiO3

Nava Setter, Nicola Marzari, Dragan Damjanovic, Ludwig Feigl, Xiankui Wei, Anand Chandrasekaran

We investigate the atomistic structure of ferroelastic-ferroelectric 90 degrees domain walls in PbTiO3 with first-principles calculations and high-resolution scanning transmission electron microscopy. We find sharp discontinuities in the variation of latti ...

Better Algorithms for LWE and LWR

Serge Vaudenay, Alexandre Raphaël Duc, Florian Tramèr

The Learning With Error problem (LWE) is becoming more and more used in cryptography, for instance, in the design of some fully homomorphic encryption schemes. It is thus of primordial importance to find the best algorithms that might solve this problem so ...

Cryptanalysis of chosen symmetric homomorphic schemes

Serge Vaudenay, Damian Vizár

Since Gentry’s breakthrough result was introduced in the year 2009, the homomorphic encryption has become a very popular topic. The main contribution of Gentry’s thesis was, that it has proven, that it actually is possible to design a fully homomorphic enc ...

An efficient many-core architecture for Elliptic Curve Cryptography security assessment

Andrea Miele, Marco Indaco

Elliptic Curve Cryptography (ECC) is a popular tool to construct public-key crypto-systems. The security of ECC is based on the hardness of the elliptic curve discrete logarithm problem (ECDLP). Implementing and analyzing the performance of the best known ...

Bringing Theory Closer to Practice in Post-quantum and Leakage-resilient Cryptography

Alexandre Raphaël Duc

Modern cryptography pushed forward the need of having provable security. Whereas ancient cryptography was only relying on heuristic assumptions and the secrecy of the designs, nowadays researchers try to make the security of schemes to rely on mathematical ...

A sieve algorithm based on overlattices

Anja Annemone Becker

In this paper, we present a heuristic algorithm for solving exact, as well as approximate, shortest vector and closest vector problems on lattices. The algorithm can be seen as a modified sieving algorithm for which the vectors of the intermediate sets lie ...

A Lattice Reduction-Aided MIMO Channel Equalizer in 90 nm CMOS Achieving 720 Mb/s

Andreas Peter Burg, Carl Christian Sten Dominic Senning

In this paper, a VLSI implementation of a complete MIMO channel equalization ASIC based on lattice reduction-aided linear detection is presented. The architecture performs preprocessing steps at channel rate and low-complexity linear data detection at symb ...
