Abstract
Derivation mechanism of a non-autonomous cross-coupled chaotic circuit is presented. In order to guarantee robust chaotic behavior of the circuit against parameter variations, ideal set of parameters are determined by constructing bifurcation diagrams. A random number generator (RNG) based on this chaotic circuit is also introduced which relies on generating non-invertible binary sequences according to regional distributions of underlying chaotic signal. Experimental results verifying the feasibility of the circuit are given. Presented RNG features much higher and constant throughput rates, allows for offset compensation and fulfills the NIST-800-22 statistical test suite without further post-processing.
