A novel hyperchaotic map and its application in fast video encryption

Abstract

By the combined feedback of exponential, cubic and sinusoidal nonlinearity, a hyperchaotic map is constructed, which has the distinct features as providing two unipolar hyperchaotic sequences and large area of hyperchaotic orbit. A fast video encryption algorithm that adopted the permutation-diffusion-permutation strategy was developed consequently based on the hyperchaotic system. Each frame image obtained from the video stream is encrypted by the algorithm in real time. To accelerate the encryption, the frame image are encrypted in parallel. Experiment results and security analysis confirm the good security, robustness, and effectiveness of the encryption algorithm.

A novel image encryption scheme based on ccnn

“…Over decades, chaos has been widely used in the field of rapid mixing of liquids [2,3], pseudo-random number generators [4,5], digital image encryption [6][7][8][9][10][11], spread spectrum communication [12], and secure communication [13,14]. The rapid development of these valuable applications is driven by creating new chaotic systems, which offer novel dynamic behaviors [15][16][17]. Encryption is one of the most widespread applications of chaotic systems [18][19][20][21][22][23][24].…”

A novel hybrid scheme for chaotic image encryption

“…In the digital age, the protection of sensitive information in the ubiquitous digital images is paramount, given their use in a wide range of personal, commercial, and medical applications and the private information contained in them is susceptible to theft by unauthorized parties [1][2][3]. Image encryption, particularly those using chaotic theory, has emerged as a robust solution to secure these images during transmission and storage [4][5][6].…”
