A parallel block-based encryption schema for digital images using reversible cellular automata

open access: yesEngineering Science and Technology, an International Journal, 2014
We propose a novel images encryption schema based on reversible one-dimensional cellular automata. Contrasting to the sequential operating mode of several existing approaches, the proposed one is fully parallelizable since the encryption/decryption tasks

Bounded Languages Meet Cellular Automata with Sparse Communication [PDF]

open access: yes, 2009
Cellular automata are one-dimensional arrays of interconnected interacting finite automata. We investigate one of the weakest classes, the real-time one-way cellular automata, and impose an additional restriction on their inter-cell communication by ...

Limit sets of stable Cellular Automata [PDF]

open access: yes, 2013
We study limit sets of stable cellular automata standing from a symbolic dynamics point of view where they are a special case of sofic shifts admitting a steady epimorphism.

BLOCK TRANSFORMATION OF HYBRID CELLULAR AUTOMATA

open access: yesJournal of Applied Analysis & Computation, 2016
Summary: By introducing a sequence-block transformation and vector-block transformation, we explore the dynamical properties of hybrid cellular automation (HCA) and hybrid cellular automation with memory (HCAM) in the framework of symbolic dynamics. As the local evolution rules of HCA and HCAM are not-uniform, the new uniform cellular automata (CAs ...

Undecidable Properties of Limit Set Dynamics of Cellular Automata [PDF]

open access: yes, 2009
Cellular Automata (CA) are discrete dynamical systems and an abstract model of parallel computation. The limit set of a cellular automaton is its maximal topological attractor. A well know result, due to Kari, says that all nontrivial properties of limit

Topological properties of cellular automata on trees [PDF]

open access: yes, 2012
We prove that there do not exist positively expansive cellular automata defined on the full k-ary tree shift (for k>=2). Moreover, we investigate some topological properties of these automata and their relationships, namely permutivity, surjectivity ...

Directed percolation in nonunitary quantum cellular automata

open access: yesPhysical Review Research, 2021
Probabilistic cellular automata (CA) provide a classic framework for studying nonequilibrium statistical physics on lattices. A notable example is the Domany-Kinzel CA, which has been used to investigate the process of directed percolation and the ...

Intrinsic Universality in Self-Assembly [PDF]

open access: yes, 2009
We show that the Tile Assembly Model exhibits a strong notion of universality where the goal is to give a single tile assembly system that simulates the behavior of any other tile assembly system.

Superintegrable cellular automata and dual unitary gates from Yang-Baxter maps

open access: yesSciPost Physics, 2022
We consider one dimensional block cellular automata, where the local update rules are given by Yang-Baxter maps, which are set theoretical solutions of the Yang-Baxter equations.
