Design and ARM-Embedded Implementation of a Chaotic Map-Based Real-Time Secure Video Communication System

Abstract

A systematic methodology is proposed for a chaotic map-based real-time video encryption and decryption system with Advanced RISC Machine (ARM)-embedded hardware implementation. According to the anti-control principle of dynamical systems, first, an 8-dimensional discrete-time chaotic map-based system is constructed, which possesses the required property of 1-1 surjection in the integer range [0, N − 1], where N denotes the number of frame pixels, suitable for position scrambling of each video frame. Then, an 8-D discrete-time hyper-chaotic system is designed for encryption-decryption of RGB tricolor pixel values. Based on the ARM-embedded platform super4412 model with Cortex-A9 processor, together with the standard QT cross-platform, an integrated chaotic map-based real-time secure video communication system is designed, implemented and evaluated. In addition, the security performance of the designed system is tested by using criteria from the NIST statistical test suite. The main feature of this method is that, both scrambling-antiscrambling of RGB tricolor pixel positions and encryption-decryption of pixel values are realized at the same time for enhancing the security. As is well known, compared with numerical simulations, hardware implementation for such a secure video communication system is very difficult to achieve, but it was successfully implemented and tested in a real world network environment by us. Both theoretical analysis and experimental results validate the feasibility and real-time performance of the new secure video communication system.

Dynamics, Circuit Design, Feedback Control of a New Hyperchaotic System and Its Application in Audio Encryption

“…Over the past 40 years, research on hyperchaotic systems [1][2][3][4][5][6] has maintained a steady pace since the first such system was reported by Rŏssler. Recently, a large number of different hyperchaotic systems have been proposed, and due to their more complex dynamics, they have found widespread applications in electronics, communications, information processing, neuroscience, and other fields, including image [29][30][31][32][33][34][35][36][37][38][39][40][41] , audio [42][43][44][45][46] , and video [47][48][49][50][51][52][53] encryption, and secure communication [54][55][56][57][58][59][60][61][62][63] .…”

Construction of a Class of High-Dimensional Discrete Chaotic Systems

“…As a complex nonlinear dynamical system and due to its significant dynamic characteristics, chaos has become a new research hotspot and has been widely used in secure communications and other research fields [1][2][3]. With the wide application of chaotic systems in secure communications, the structures of chaotic system problems have attracted increasing attention from scholars [4][5][6], and a new chaotic system can provide a new pseudorandom number generator, which can be further applied to the design of cryptosystems [4,[6][7][8]. Continuous system discretization is needed for actual use cases, and the direct use of discrete chaos is a very good choice.…”

“…In general, in the process of designing chaotic cryptosystems, high-dimensional systems have attracted increasing interest from researchers because of their highly complex dynamic properties, but the constructions and theoretical proofs of high-dimensional discrete chaotic systems are always difficult. Most of the existing high-dimensional discrete chaotic systems are designed based on the necessary conditions of the chaotic systems, such as having a positive Laypunov exponent [5][6][7]. According to the Marotto theorem, sufficient conditions that an n-dimensional discrete system is a chaotic system can be given.…”
