Physical Side-Channel Attacks and Covert Communication on FPGAs: A Survey

Mirjana Stojilovic, Seyedeh Sharareh Mirzargar

Field-programmable gate arrays (FPGAs) are, like CPUs, susceptible to side-channel information leakage and covert communication. The malleability of FPGAs enables users to create and control physical effects, and sense and measure the consequences. With FP ...

Spatial multiplexing of soliton microcombs

Tobias Kippenberg, Maxim Karpov, Erwan Guillaume Albert Lucas, Arslan Sajid Raja, Romain Dany Bruno Bouchand

Dual-comb interferometry utilizes two optical frequency combs to map the optical field's spectrum to a radio-frequency signal without using moving parts, allowing improved speed and accuracy. However, the method is compounded by the complexity and demandin ...

Towards More Accurate Radio Telescope Images

Paul Hurley, Matthieu Martin Jean-André Simeoni

Radio interferometry usually compensates for high levels of noise in sensor/antenna electronics by throwing data and energy at the problem: observe longer, then store and process it all. We propose instead a method to remove the noise explicitly before ima ...

Design of LDPC Codes for the Unequal Power Two-User Gaussian Multiple Access Channel

Alexios Konstantinos Balatsoukas Stimming

In this letter, we describe an LDPC code design framework for the unequal power two-user Gaussian multiple access channel using EXIT charts. We show that the sumrate of the LDPC codes designed using our approach can get close to the maximal sum-rate of the ...

A Dynamically Reconfigurable Platform for High-Performance and Low-Power On-Board Processing

Paolo Ienne, Andrea Guerrieri, Sahand Kashani

FPGAs (Field Programmable Gate Array) are an attractive technology for high-speed data processing in space missions due to their unbeatable flexibility and best performance-to-power ratio in comparison to software. However FPGAs suffer from 3 major drawbac ...

Microresonator-based solitons for massively parallel coherent optical communications

Tobias Kippenberg, Maxim Karpov, Martin Hubert Peter Pfeiffer, Arne Kordts, Victor Brasch, Miles Henry Anderson

Solitons are waveforms that preserve their shape while propagating, as a result of a balance of dispersion and nonlinearity(1,2). Soliton-based data transmission schemes were investigated in the 1980s and showed promise as a way of overcoming the limitatio ...

Single-FPGA complete 3D and 2D medical ultrasound imager

Jean-Philippe Thiran, Giovanni De Micheli, Federico Angiolini, Aya Mohamed Naguib Ahmed Ibrahim, Marcel Arditi, Damien Doy

3D ultrasound (US) acquisition acquires volumetric images, thus alleviating a classical US imaging bottleneck that requires a highly-trained sonographer to operate the US probe. However, this opportunity has not been explored in practice, since 3D US machi ...
