Swap and Rotate: Lightweight Linear Layers for SPN-based Blockciphers

Serge Vaudenay, Francesco Regazzoni, Subhadeep Banik, Muhammed Fatih Balli

In CHES 2017, Jean et al. presented a paper on "Bit-Sliding" in which the authors proposed lightweight constructions for SPN based block ciphers like AES, PRESENT and SKINNY. The main idea behind these constructions was to reduce the length of the datapath ...

Triboelectric‐TFT Flip‐Flop for Bistable Latching of Dielectric Elastomer Actuators

Danick Briand, Herbert Shea, Rubaiyet Iftekharul Haque, Alexis Pierre Henri Marette, Xiaobin Ji, Ronan Julien Hinchet

A high‐voltage flip‐flop combining two self‐powered soft sensors with a flexible high‐voltage thin film transistor (HVTFT) is reported, and is used to electrically latch dielectric elastomer actuators (DEAs) in zero and high‐strain states. Two touch‐actuat ...

Compact Circuits for Combined AES Encryption/Decryption

Subhadeep Banik

The implementation of the AES encryption core by Moradi et al. at Eurocrypt 2011 is one of the smallest in terms of gate area. The circuit takes around 2400 gates and operates on an 8 bit datapath. However this is an encryption only core and unable to cate ...

Rock You like a Hurricane: Taming Skew in Large Scale Analytics

Willy Zwaenepoel, Nicolas Schiper, Laurent Bindschaedler, Jasmina Malicevic, Ashvin Goel

Current cluster computing frameworks suffer from load imbalance and limited parallelism due to skewed data distributions, processing times, and machine speeds. We observe that the underlying cause for these issues in current systems is that they partition ...

Clock-Gating of Streaming Applications for Energy Efficient Implementations on FPGAs

Marco Mattavelli, Endri Bezati, Simone Casale Brunet

This paper investigates the reduction of dynamic power for streaming applications yielded by asynchronous dataflow designs by using clock gating techniques. Streaming applications constitute a very broad class of computing algorithms in areas such as signa ...

Spinor stochastic resonance

Benoît Marie Joseph Deveaud, François Morier-Genoud, Marcia Portella Oberli, Stéphane Trebaol, Hadis Abbaspour

We report on noise-induced spin ordering in a collective quasiparticle system: spinor stochastic resonance. Synergetic interplay of a polarization-modulated signal and a polarization noise allows us to switch coherently between the two metastable states of ...

Effects of Process Variations on 3-D Global Clock Distribution Networks

Giovanni De Micheli, Hu Xu, Vasileios Pavlidis

In three-dimensional (3D) integrated circuits, the effect of process variations on clock skew differs from 2D circuits. The combined effect of inter-die and intra-die process variations on the design of 3D clock distribution networks is considered in this ...

Skew Variability in 3-D ICs with Multiple Clock Domains

Giovanni De Micheli, Hu Xu, Vasileios Pavlidis

The effect of process variations on the clock skew in three dimensional (3-D) circuits with multiple clock domains is investigated. In 3-D ICs, the combined effect of inter-die and intra-die process variations should be considered in the design of clock di ...

On Zero-Dimensional Exciton-Polaritons

Roland Cerna

Microcavity exciton-polaritons are half-matter half-light quasiparticles with outstanding properties. This offers a great way to access and control fundamental excitations in a solid by simple optical means. Therefore, apart from their importance in fundam ...

Constructing de Sitter vacua in no-scale string models without uplifting

Claudio Scrucca

We develop a method for constructing metastable de Sitter vacua in N = 1 supergravity models describing the no-scale volume moduli sector of Calabi-Yau string compactifications. We consider both heterotic and orientifold models. Our main guideline is the n ...

How to solve consensus in the smallest window of synchrony

Rachid Guerraoui, Seth Gilbert, Dan Alistarh

This paper addresses the following question: what is the minimum-sized synchronous window needed to solve consensus in an otherwise asynchronous system? In answer to this question, we present the first optimally-resilient algorithm ASAP that solves consens ...
