One of the main obstacles for the wider deployment of radio (RF) distance bounding is the lack of platforms that implement these protocols. We address this problem and we build a prototype system that demonstrates that radio distance bounding protocols can be implemented to match the strict processing that these protocols require. Our system implements a prover that is able to receive, process ...

We consider the nonlinear function used in the Advanced Encryption Standard (AES). This nonlinear function is essentially inversion in the finite field GF(2), which is most naturally considered as a projective transformation. Such a viewpoint allows us to demonstrate certain properties of this AES nonlinear function. In particular, we make some comments about the group generated by such transfo...

Backpropagation is one of the most famous training algorithms for multilayer perceptrons. Unfortunately it can be very slow for practical applications. Over the last years many improvement strategies have been developed to speed up backpropagation. It’s very difficult to compare these different techniques, because most of them have been tested on various specific data sets. Most of the reported...

CVT and XOR are two binary operations together used to calculate the sum of two non-negative integers on using a recursive mechanism. In this present study the convergence behaviors of this recursive mechanism has been captured through a tree like structure named as CVT-XOR Tree. We have analyzed how to identify the parent nodes, leaf nodes and internal nodes in the CVT-XOR Tree. We also provid...

In this paper, we propose a 128-bit block cipher ARIA which is an involution substitution and permutation encryption network(SPN). We use the same S-boxes as Rijndael to eliminate defects which are caused by a totally involution structure. In the diffusion layer of ARIA, a 16×16 binary matrix of the maximum branch number 8 is used to avoid some attacks well applied to the reduced round of Rijnd...

The perfect phylogeny model for haplotype evolution has been successfully applied to haplotype resolution from genotype data. In this study we explore the application of the perfect phylogeny model to other problems in the design and analysis of genetic studies. We consider a novel type of data, xor-genotypes, which distinguish heterozygote from homozygote sites but do not identify the homozygo...

An inhomogeneous cellular automaton is considered consisting of two two-dimensional planes, one of which contains the t ransition functions or programs and the other the evolving data. Wi th a two-level hierarchy, basic experiments are performed with quenched and a nnealed XOR and AND functions . These funct ions were dist r ibuted both at random a nd with correla ti ons produced by a Glauber a...
