On the Use of Memristive Hyperchaotic System to Design Color Image Encryption Scheme

Abstract

In this paper a novel encryption scheme based on memristive hyperchaotic system was proposed. Firstly, combined with SHA-512 hash function and plain image, key sequences can be generated by iterating the memristive hyperchaotic system. Then, permutation operation and diffusion operation are performed for each row and column of the plain image. Finally, a serious of simulation experiments are conducted to evaluate the proposed encryption scheme, showing that the proposed scheme has well performance. Further, NIST SP800-22 test results show that the randomness of the hyperchaotic pseudorandom sequence used by the algorithm is better than the general linear congruence pseudorandom sequence.

An observer design for Takagi-Sugeno fuzzy bilinear control systems

“…Oscillators [1][2][3], memristors [4][5][6], circuits [7][8][9], encryption [10,11], cryptosystems [12][13][14], and fuzzy systems [15,16] are some popular areas where hyperchaotic systems find applications owing to the high complexity in their dynamics.…”

Tri-Valued Memristor-Based Hyper-Chaotic System with Hidden and Coexistent Attractors

“…It shows many unique properties such as initial sensitivity and ergodicity. Since the first chaotic system was designed by Lorenz in 1963 [1], researchers have developed many chaotic systems and applied them to a wide body of research fields such as dynamics research [2], neural networks [3], secure communication [4][5][6], image encryption [7][8][9][10][11].…”
