In the literature, little attention is paid to devising and analyzing novel one dimensional chaotic mappings. In our previous efforts, we have tried fold, translation & scale on arctangent function & sigmoid function respectively, which brings good results. In this paper, we do the same to obtain a variant of Hyperbolic Cosine Function. Both Bifurcation Diagram & Lyapunov Exponent Spectrum manifest that the new mapping possesses wonderful chaotic properties. Then, a pseudorandom bit generator is designed based on it. Pseudorandom tests demonstrate that the generator is much better than our previous ones. It owns great application prospect.
Key words: Chaotic mapping / Hyperbolic cosine function / Pseudorandom bit generator
