In this paper, A generalized chaotic map based on parabola functions were presented.
Chaotic dynamics were described in terms of apparent in time-domain, and both qualitatively and quantitatively examination using bifurcation diagram and Lyapunov exponents.
The PRNG which utilized the proposed parabola chaotic maps were also demonstrated and evaluation result of the random bit sequences were evaluated using the standard NIST SP800-22 test suite and pass all the tests.

The random bit output of the proposed PRNG has been examined using the standard NIST SP800-22 test suite. The test can be used to analyse the number sequence by identifying any pattern of value that indicates non-randomness within the sequences. through the probability values (P-value). The test is considered to be passed for P-values greater than 0.01; otherwise, they are rejected. The proportion indicates the ratio of sequences passing a specific test.

To Maximize the level of randomness, The threshold value of the Entropy Harvester is carefully chosen at the highest level of randomness which is calculated using Shannon’s Entropy.

The proposed architecture of the PRNG was designed using the Absolute value function-based parabola chaotic map as an Entropy Source, while a Comparator with a threshold value was used as an Entropy Harvester, and lastly, an 8-bit Fibonacci linear feedback shift register (LFSR) was used as a Post Processor.

As a practical example, a PRNG based on the proposed Chaotic Map was also included in this work. A Random Number Generator (RNG) is a computational algorithm or device that generates numbers or sequences of numbers that appear random or unpredictable.

These are the Bifurcation diagrams and Lyapunov exponent (LE) plots of the proposed chaotic map that's based on the Absolute function, where A = 1.8 and B = 1. And we can see that with the Absolute function the proposed chaotic map can offer robust dynamics.

However, in my study, I have realized a new chaotic map. The proposed chaotic map can be defined by the simple mathematical Which is a conjugation of 2 chaotic map Where the fNL(x) can be any nonlinear function with a Parabolic Shape.

There are many chaotic maps proposed in the past especially the Discrete-Time chaotic map such as Logistic Map or Gauss Iterated Map.

There are 3 main Key Properties of the Chaotic system. First the extremely sensitive to the initial conditions, second is the trajectory of systems that never repeats and lastly, all chaotic systems are nonlinear.

Chaos theory is a mathematical field of study which states that nonlinear dynamical systems that are seemingly random are actually deterministic from much simpler equations.
