A cellular automaton (CA) is a discrete model for a spatiotemporal phenomenon. In a CA, an infinite number of cells are placed uniformly in the space, and each cell changes its state depending on its neighboring cells by a local function. Applying the local function to all the cells in parallel, a global function is induced, by which the configuration ...

Reversible cellular automata image encryption for similarity search
Signal Processing: Image Communication, 2019With the development of cloud computing, people prefer to outsource images to cloud service for saving storage and convenient retrieval. For privacy-preserving purposes, sensitive images, such as medical and personal images, need to be encrypted before ...

Two-Dimensional Universal Reversible Cellular Automata
, 2017The problem of constructing Turing universal reversible one-dimensional cellular automata (RCAs) is studied. First, methods of designing three-neighbor and two-neighbor reversible partitioned CAs (RPCAs) that directly simulate a given reversible Turing machine (RTM) are shown. Since RPCAs are a subclass of RCAs, we see the class of one-dimensional RCAs

An Block Image Encryption Algorithm Based on Reversible Cellular Automata
International Conference on Speech Technology and Human-Computer Dialogue, 2021This article proposed a block image encryption scheme based on reversible cellular automata (RCA) and chaotic systems in order to construct an image encryption scheme with great confidentiality effect and high encryption and decryption efficiency. In the

Clustering Using Cyclic Spaces of Reversible Cellular Automata
Complex Systems, 2021This paper introduces a cycle-based clustering technique using the cyclic spaces of reversible cellular automata (CAs). Traditionally, a cluster consists of close objects, which in the case of CAs necessarily means that the objects belong to the same ...
