Construction of Cryptographically Secure AES S-Box using Second-order Reversible Cellular Automata

Journal of Intelligent & Fuzzy Systems, 2020
In cryptography the block ciphers are the mostly used symmetric algorithms. In the existing system the standard S-Box of Advanced Encryption Standard(AES) is performed using the irreducible polynomial equation in table form known as look-up tables(LUTs).

Reversible Cellular Automata and Statistical Mechanics

Physical Review Letters, 1987
Reversible cellular automata are used to investigate the thermodynamic behavior of large systems. Additive conserved quantities are regarded as the energy of these models. By the consideration of a large system as the sum of a subsystem and a heat bath, it is numerically shown that a canonical distribution is realized under certain conditions ...

Generalized Reversibility of Cellular Automata

2019
Reversibility is a fundamental property of microscopic physical systems, implied by the laws of quantum mechanics, which seems to be at odds with the Second Law of Thermodynamics (Schiff 2008; Toffoli and Margolus 1990). Nonreversibility always implies energy dissipation, in practice, in the form of heat.

REVERSIBILITY OF A SYMMETRIC LINEAR CELLULAR AUTOMATA

International Journal of Modern Physics C, 2009
The characterization of the size of the cellular space of a particular type of reversible symmetric linear cellular automata is introduced in this paper. Specifically, it is shown that those symmetric linear cellular with 2k + 1 cells, and whose transition matrix is a k-diagonal square band matrix with nonzero entries equal to 1 are reversible ...

Resolution Scalable Image Coding With Reversible Cellular Automata

IEEE Transactions on Image Processing, 2011
In a resolution scalable image coding algorithm, a multiresolution representation of the data is often obtained using a linear filter bank. Reversible cellular automata have been recently proposed as simpler, nonlinear filter banks that produce a similar representation.

Reversible Cellular Automata

2005
Reversible cellular automata (RCA) are models of massively parallel computation that preserve information. This paper is a short survey of research on reversible cellular automata over the past fourty plus years. We discuss the classic results by Hedlund, Moore and Myhill that relate injectivity, surjectivity and reversibility with each other.

Computation in reversible cellular automata

International Journal of General Systems, 2012
A reversible cellular automaton (RCA) is a subclass of a CA such that its global function is injective. It is considered as an abstract spatiotemporal model of a reversible physical system. In spite of the strong constraint of reversibility, an RCA has a high ability of information processing.

Encryption based on reversible cellular automata

IEEE 2002 International Conference on Communications, Circuits and Systems and West Sino Expositions, 2003
With the development of information technology, information security as well as the implementation of encryption systems becomes more and more complex, and therefore new methods are explored to simplify the complexity of the implementation. Cellular automata (CA) have the characteristics of simplicity of basic components, locality of CA interactions ...

Pattern formation in reversible cellular automata

Journal of Physics A: Mathematical and General, 1986
The authors analyse the dynamics of pattern formation in two examples of reversible cellular automata which have been argued to belong to the critical dynamics universality class of the kinetic Ising model. The results obtained suggest that their dynamical evolution is different from the analogous kinetic Ising model.
