Cryptanalysis of KLEIN (Full version)
KLEIN lightweight block cipher truncated differential cryptanalysis
2016/1/26
Due to the recent emergence of resource-constrained devices, cryptographers are
facing the problem of designing dedicated lightweight ciphers. KLEIN is one of the resulting
primitives, proposed at R...
An Improved Truncated Di fferential Cryptanalysis of KLEIN
KLEIN Truncated Differential Attack
2016/1/9
KLEIN is a family of lightweight block ciphers which proposed
at RFIDSec 2011 by Gong et al. It has a 64-bit state and 64, 80 or
96-bit key size which introduce its version. It uses 16 same 4-bit Sb...
Breather statics and dynamics in Klein-Gordon chains with a bend
Nonlinear model the model of the power of the bending Angle scattering
2014/12/29
In this paper, we examine a nonlinear model with an impurity emulating a bend. We justify the geometric interpretation of the model and connect it with earlier work on models including geometric effec...
Asymptotic behaviour of small solutions for the discrete nonlinear Schrödinger and Klein–Gordon equations
Discrete schrodinger propagator klein Gordon equation form the analysis of decay estimate
2014/12/29
We show decay estimates for the propagator of the discrete Schrödinger and Klein–Gordon equations in the form {{\| {U(t)f} \|}_{{l^\infty}}} \leq C (1+|t|)^{-d/3}{{\| {f} \|}_{{l^1}}} . This impl...
Discrete Klein–Gordon models with static kinks free of the Peierls–Nabarro potential
Gordon type model nonlinear klein discretization static kink lattice the discrete model
2014/12/25
For the nonlinear Klein–Gordon type models, we describe a general method of discretization in which the static kink can be placed anywhere with respect to the lattice. These discrete models are, there...
Standard nearest-neighbour discretizations of Klein–Gordon models cannot preserve both energy and linear momentum
Discrete nonlinear klein GeDengBo equation the standard discrete linear momentum
2014/12/25
We consider nonlinear Klein–Gordon wave equations and illustrate that standard discretizations thereof (involving nearest neighbours) may preserve either standardly defined linear momentum or standard...

Linear stability chain coupled oscillator soft nonlinear coupling
2014/12/24
In this paper, a theorem, which determines the linear stability of multibreathers excited over adjacent coupled oscillators in Klein–Gordon chains, is proven. Specifically, it is shown that for soft n...
Multibreather and vortex breather stability in Klein–Gordon lattices: Equivalence between two different approaches
Multibreather configuration stability discrete respirator the coupled oscillator
2014/12/24
In this work, we revisit the question of stability of multibreather configurations, i.e., discrete breathers with multiple excited sites at the anti-continuum limit of uncoupled oscillators. We presen...

We consider how variations in the moduli of the compactification manifold contribute `pdV' type work terms to the first law for Kaluza-Klein black holes. We give a new proof for the S1 case, based on ...

2014/12/20
We study the thermodynamics of Kaluza-Klein black holes with momentum along the compact dimension, but vanishing angular momentum. These black holes are stationary, but non-rotating. We derive the fir...
