AbstractIn this study a novel four dimensional (4D) chaotic system is introduced. To prove chaotic behavior of the system, time series and phase portraits are presented. A novel pseudo random number generator (PRNG) application of the chaotic system is realized to show the system is suitable for engineering applications like encryption and data hiding. In order to realize PRNG, the chaotic system is discretized with numerical methods. The next step is selection of different number of bits from different state variables obtained from the chaotic system. NIST 800-22 statistical tests, the highest international standard, are performed for the generated random numbers to prove the proposed PRNG has sufficient randomness and successful results are obtained.
