Random Number Generation using Chaotic Circuits

In this paper, the use of a chaotic circuit - namely, Chua’s Circuit - is explored as a possible method of random number generation. Using the chaotic nature of the output and the sensitive dependence on initial conditions, random binary bits were generated and compared against the output of known state-of-the-art Pseudo-Random-Number-Generators (PRNGs) and with those of a True-Random-Number-Generator (TRNG) using known statistical tests for random- ness. The results were used understand the randomness of the values generated, and to draw conclusions for the possible application of Chua Circuits as RNGs for encryption.

Emergence of Randomness from Chaos

International Journal of Bifurcation and Chaos, 2012

In systems theory and science, emergence is the way complex systems and patterns arise out of a multiplicity of relatively simple interactions. Emergence is central to the theories of integrative levels and of complex systems [Aziz-Alaoui & Bertelle, 2009]. In this paper, we use the emergent property of the ultra weak multidimensional coupling of p 1-dimensional dynamical chaotic systems which leads from chaos to randomness. Generation of random or pseudorandom numbers, nowadays, is a key feature of industrial mathematics. Pseudorandom or chaotic numbers are used in many areas of contemporary technology such as modern communication systems and engineering applications. More and more European or US patents using discrete mappings for this purpose are obtained by researchers of discrete dynamical systems [Petersen & Sorensen, 2007; Ruggiero et al., 2006]. Efficient Chaotic Pseudo Random Number Generators (CPRNG) have been recently introduced. They use the ultra weak multidimensional c...
