SHAH: Hash Function based on Irregularly Decimated Chaotic Map

Abstract

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.

“…proposals for a stream-and-block hybrid encryption based on chaos [32]. Using chaotic maps to create hash functions has taken the lion's share of the chaos application in cryptography [33][34][35][36]. Permutation of image pixels is a widely used encryption technique; a large number of works have used chaotic maps for image pixel permutation [37][38][39].…”
