A discrete chaotic multimodel based on 2D Hénon maps

چکیده
In this paper, we propose to design a new family of discrete-time chaotic systems based on the use of the multimodel approach. This approach is used to represent a way to generate new family of discrete-time chaotic systems, from p discrete time chaotic basis models. Our results are illustrated on the specific case of a new discrete-time chaotic multimodel based on two chaotic 2D Hénon maps with two different sets of parameters leading to different behaviors. The chaos characterization of obtained multimodels is performed using bifurcation diagrams.

متن کاملA New RGB Image Encryption based on a Combination of 2D Chaotic Maps
In this paper a new approach for RGB image encryption is based on a blend of 2D chaotic maps. Chaotic Henon map, chaotic Burger map and chaotic Gingerbreadman map is used in order to meet up the requirements of the protected image transmission. The proposed image encryption scheme is composed of two Transformation processes and two substitution processes. Different statistical methods, such as ...
متن کاملZero entropy Hénon-like maps depend on infinitely many parameters
In the family of area-contracting Hénon-like maps with zero topological entropy we show that there are maps with infinitely many moduli of stability. Thus one cannot find all the possible topological types for non-chaotic area-contracting Hénon-like maps in a family with finitely many parameters. A similar result, but for the chaotic maps in the family, became part of the folklore a short time ...
متن کاملIdentity-based encryption and digital signature schemes using extended chaotic maps
This paper designed a new extended chaotic map-based Identity-based encryption (ECM-IBE) scheme and Identitybased digital signature (ECM-IDS) scheme using extended chaotic maps. The security of the ECM-IBE scheme is based on the hardness assumption of chaotic maps-based decisional DiffieHellman (CDDH) problem, whereas the ECM-IDS scheme is secure based on the difficulties of chaotic maps-based ...
متن کاملA unified piecewise smooth chaotic mapping that contains the Hénon and the Lozi systems
In this paper we introduce a new piecewise smooth mapping of the plane as a unified discrete-time chaotic system that contains the original H ́enon and Lozi systems as two extremes and other systems as a transition in between and that has robust homoclinic chaos over a portion of its key system parameters. Dynamical behaviors of the unified system are investigated in some detail.
