BentSign: keyed hash algorithm based on bent Boolean function and chaotic attractor [PDF]
Bulletin of the Polish Academy of Sciences: Technical Sciences, 2019 In this study, we propose a novel keyed hash algorithm based on a Boolean function and chaotic attractor. The hash algorithm called BentSign is based on two Signature attractors and XOR function and a bent Boolean function.

Compactness of Hashing Modes and Efficiency beyond Merkle Tree [PDF]
arXiv, 2021 We revisit the classical problem of designing optimally efficient cryptographically secure hash functions. Hash functions are traditionally designed via applying modes of operation on primitives with smaller domains. The results of Shrimpton and Stam (ICALP 2008), Rogaway and Steinberger (CRYPTO 2008), and Mennink and Preneel (CRYPTO 2012) show how to ...

On the power of memory in the design of collision resistant hash functions [PDF]
, 1993 Collision resistant hash functions are an important basic tool for cryptographic applications such as digital signature schemes and integrity protection based on “fingerprinting”. This paper proposes a new efficient class of hash functions based on a block cipher that allows for a tradeoff between security and speed.

Coulomb drag between ballistic quantum wires
, 2012 We develop a kinetic equation description of Coulomb drag between ballistic one-dimensional electron systems, which enables us to demonstrate that equilibration processes between right- and left-moving electrons are crucially important for establishing ...

Modeling and tackling resistivity scaling in metal nanowires [PDF]
, 2015 A self-consistent analytical solution of the multi-subband Boltzmann transport equation with collision term describing grain boundary and surface roughness scattering is presented to study the resistivity scaling in metal nanowires. The different scattering mechanisms and the influence of their statistical parameters are analyzed.

A simple Solvable Model of Body Motion in a One-dimensional Resistive Medium [PDF]
arXiv, 2001 We introduce and solve in closed form a simple model of a macroscopic body propagating in a one-dimensional resistive medium at temperature T. The assumption of completely inelastic collisions between the body and the particles composing the medium leads to a resistive force that is opposite and proportional to the square of the body's ...
