SCARE of an Unknown Hardware Feistel Implementation [PDF]

, 2008
Physical attacks based on Side Channel Analysis (SCA) or on Fault Analysis (FA) target a secret usually manipulated by a public algorithm. SCA can also be used for Reverse Engineering (SCARE) against the software implementation of a private algorithm. In this paper, we claim that an unknown Feistel scheme with an hardware design can be recovered with a

Stability of Medicinal Nanoemulsions to Spaceflight: Insights From the StarMed Experiment

Advanced Healthcare Materials, EarlyView.
Chitosan‐coated melatonin nanoemulsions (MN) recovered from a sounding rocket mission preserve droplet size and controlled‐release behavior, whereas uncoated nanoemulsions show ageing‐driven droplet growth and increased accessible drug fraction. Simple polymer coatings thus enhance the flight resilience of liquid space medicines under cumulative launch

Hardware Implementations of Fixed-Point Atan2

2015 IEEE 22nd Symposium on Computer Arithmetic, 2015
—The atan2 function computes the polar angle arctan(x/y) of a point given by its cartesian coordinates. It is widely used in digital signal processing to recover the phase of a signal. This article studies for this context the implementation of atan2 with fixed-point inputs and outputs.
