Some observations on HC-128
In this paper, we use linear approximations of the addition modulo 2n of three n-bit integers to identify linear approximations of g1, g2, the feedback functions of HC-128. This, i...

A Refactoring Approach to Parallelism
—In the multicore era, a major programming task will be to make programs more parallel. This is tedious because it requires changing many lines of code, and it is error-prone and...

Bounds on the efficiency of black-box commitment schemes
Constructions of cryptographic primitives based on general assumptions (e.g., one-way functions) tend to be less efficient than constructions based on specific (e.g., number-theor...

Decision-Feedback Differential Detection in Impulse-Radio Ultra-Wideband Systems
—Building upon recent approaches for detection of impulse-radio ultra-wideband (IR-UWB) based on compressed sensing (CS), we combine this approach with techniques known from adva...

Blurring-Invariant Riemannian Metrics for Comparing Signals and Images
We propose a novel Riemannian framework for comparing signals and images in a manner that is invariant to their levels of blur. This framework uses a log-Fourier representation of...
