Effect of Different Chaotic Maps on a Chaotic Block Cipher Algorithm for Image Cryptosystems
Main Article Content
Abstract
In this paper, we provide analysis details of the algorithm set forth by Mohamed Amin et al. [Commun. Nonlinear Sci. Numer. Simulat. 15 (2010) 3484-97]. They proposed a block cipher algorithm using chaotic Tent map. For our analysis, besides the Tent map we have used 3 different maps viz. Hénon map, Gauss iterated map and Tinkerbell Map individually. We have provided experimentation results of statistical and differential analysis of the algorithm using the said chaotic maps.
