Machine learning for fast and reliable solution of time-dependent differential equations

Alfio Quarteroni, Francesco Regazzoni

We propose a data-driven Model Order Reduction (MOR) technique, based on Artificial Neural Networks (ANNs), applicable to dynamical systems arising from Ordinary Differential Equations (ODEs) or time-dependent Partial Differential Equations (PDEs). Unlike ...

Active contraction of cardiac cells: a reduced model for sarcomere dynamics with cooperative interactions

Alfio Quarteroni, Luca Dede', Francesco Regazzoni

We propose a reduced ODE model for the mechanical activation of cardiac myofilaments, which is based on explicit spatial representation of nearest-neighbour interactions. Our model is derived from the cooperative Markov Chain model of Washio et al. (Cell M ...

Rethinking Secure FPGAs: Towards a Cryptography-friendly Configurable Cell Architecture and its Automated Design Flow

Edoardo Charbon, Francesco Regazzoni

This work proposes the first fine-grained configurable cell array specifically tailored for the implementation of cryptographic algorithms that can be configured using widely adopted hardware description languages. Our solution can be added as a small, cry ...

Towards Low Energy Stream Ciphers

Willi Meier, Francesco Regazzoni, Subhadeep Banik

Energy optimization is an important design aspect of lightweight cryptography. Since low energy ciphers drain less battery, they are invaluable components of devices that operate on a tight energy budget such as handheld devices or RFID tags. At Asiacrypt ...

Inverse Gating for Low Energy Block Ciphers

Francesco Regazzoni, Subhadeep Banik

In this paper we explore the technique of “inverse gating” which is a significant improvement over the ”round gating” technique introduced in HOST 2016. Round gating worked by generating timing signals to separate glitch propagation from one circuit elemen ...

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 ...

Automatic Application of Power Analysis Countermeasures

Paolo Ienne, Philip Brisk, Francesco Regazzoni, Ali Galip Bayrak, David Novo Bruna

We introduce a compiler that automatically inserts software countermeasures to protect cryptographic algorithms against power-based side-channel attacks. The compiler first estimates which instruction instances leak the most information through side-channe ...

A 65k pixel, 150k frames-per-second camera with global gating and micro-lenses suitable for fluorescence lifetime imaging

Claudio Bruschini, Edoardo Charbon, Samuel Burri, Francesco Regazzoni, François Eric Powolny

This paper presents our work on a 65k pixel single-photon avalanche diode (SPAD) based imaging sensor realized in a 0.35 mu m standard CMOS process. At a resolution of 512 by 128 pixels the sensor is read out in 6.4ps to deliver over 150k monochrome frames ...

Architecture and applications of a high resolution gated SPAD image sensor

Claudio Bruschini, Edoardo Charbon, Samuel Burri, Francesco Regazzoni

We present the architecture and three applications of the largest resolution image sensor based on single-photon avalanche diodes (SPADs) published to date. The sensor, fabricated in a high-voltage CMOS process, has a resolution of 512 x 128 pixels and a p ...

Comparison of Two Cameras based on Single Photon Avalanche Diodes (SPADs) for Fluorescence Lifetime Imaging Application with Picosecond Resolution

Claudio Bruschini, Edoardo Charbon, Samuel Burri, Francesco Regazzoni, François Eric Powolny

We report on a comparative study of two time-resolved cameras based on digital Single Photon Avalanche Diodes (SPADs) for Fluorescen ce Lifetime Imaging applications. In contrast to standard imagers such as cameras, SPAD imagers provide intensity as well a ...

Towards a High-Speed Quantum Random Number Generator

Edoardo Charbon, Samuel Burri, Francesco Regazzoni

Randomness is of fundamental importance in various fields, such as cryptography, numerical simulations, or the gaming industry. Quantum physics, which is fundamentally probabilistic, is the best option for a physical random number generator. In this articl ...

Power-gated MOS current mode logic (PG-MCML): a power aware DPA-resistant standard cell library

Paolo Ienne, Yusuf Leblebici, Stéphane Badel, Francesco Regazzoni

MOS Current Mode Logic (MCML) is one of the most promising logic style to counteract power analysis attacks. Unfortunately, the static power consumption of MCML standard cells is significantly higher compared to equivalent functions implemented using stati ...

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

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

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 ...
