Yet Another Pseudorandom Number Generator

We propose a novel pseudorandom number generator based on R\"ossler attractor and bent Boolean function. We estimated the output bits properties by number of statistical tests. The results of the cryptanalysis show that the new pseudorandom number generation scheme provides a high level of data security.Comment: 5 pages, 7 figures; to be published in International Journal of Electronics and Telecommunications, vol.63, no.

Least Significant Bit Steganography using Hitzl-Zele Chaotic Map

We propose a novel least significant bit steganography algorithm based on a Hitzl-Zele chaotic function. Exact study has been provided on the novel scheme using visual inspection, peak signal-to-noise ratio, and histogram analysis.

The steganographic analysis includes files comparison, histogram analysis, Peak to signal noise ratio and Chi-square analysis

A Novel Pseudorandom Bit Generator Based on Chirikov Standard Map Filtered with Shrinking Rule

This communication proposes a simplified model of pseudorandom bit generator, based on two Chirikov standard maps filtered with shrinking rule. The study also demonstrates that the generated keystreams have excellent properties of randomness and resistance to statistical attacks, which is proven by using the NIST, ENT, and DIEHARD testing suites

SHAH: Hash Function based on Irregularly Decimated Chaotic Map

In this paper, we propose a novel hash function based on irregularly decimated chaotic map. The hash function called SHAH is based on two Tinkerbell maps filtered with irregular decimation rule. Exact study has been provided on the novel scheme using distribution analysis, sensitivity analysis, static analysis of diffusion and confusion, and collision analysis. The experimental data show that SHAH satisfied admirable level of security.Comment: accepted for publication in International Journal of Electronics and Telecommunications, vol. 6
