dc.description.abstractIn the recent past, various algorithms for image encryption is introduced based on chaotic systems, some of them appeared weak in some points such as, resisting the chosen plaintext attack and the chosen ciphertext attack with low sensitivity to change of plain images. To overcome such weaknesses, this article proposes a new two-dimensional (2D) hyperchaotic system, which is derived from three maps namely; Henon, logistic, iterative chaotic map with infinite collapse (ICMIC) maps. The performance analysis of this system shows high sensitivity to the initial condition, complicated dynamics, hyperchaotic properties, and better ergodicity. The proposed system is adopted in the design of a new image encryption algorithm. The encryption process is mainly depending on changing of eigenvalues and eigenvectors of original image utilizing a function to change the intensity of pixels, the plain-image is divided into blocks to generate four different keys (multi-key) based on the proposed hyperchaotic system to increase the complexity and reduce the computation time. The partitioned process is repeated several times for each block before obtaining an encrypted image, where the new block in each iteration is multiplied with the four different generated keys. Eventually, to show the efficiency of the encryption image, some performance analysis tests are performed such as; image histogram, NPCR, UACI and pixels correlation.en_US
