“…Therefore, the researches in this field turn to high dimensional chaotic system [9]. Fu developed an improved image encryption algorithm based on 3D Lorenz chaotic system [10]. In order to obtained chaotic sequence, these schemes must solve the equations with a certain numerical quadrature method, such as Runge-Kutta algorithm, which will reduce efficiency of image encryption method.…”

In the paper, a cross chaotic map using Logistic map and Chebyshev map is presented. With the exceptionally desirable properties of non-periodical motion and non-convergence of chaos, scheme for image encryption has suggested a new and efficient way to deal with the intractable problem of fast and highly secure image. In order to realize image encryption, every pixel of image is randomly changed according to encryption matrix in the process of grayscale substitution; simultaneously scrambling transformation technique (row rotation and column rotation technique) is used in the process of position permutation. The experimental results indicate the scheme is more secure and efficient than conventional ones, and it is feasible.

Abstract-Recently, a pixel-chaotic-shuffling (PCS) method has been proposed by Huang et al. for encrypting color images using multiple chaotic systems like the Henon, the Lorenz, the Chua, and the Rossler systems. All of which have great encryption performance. The authors claimed that their pixel-chaotic-shuffle (PCS) encryption method has high confidential security. However, the security analysis of the PCS method against the chosen-plaintext attack (CPA) and known-plaintext attack (KPA) performed by Solak et al. successfully breaks the PCS encryption scheme without knowing the secret key. In this paper we present an improved shuffling pattern for the plaintext image bits to make the cryptosystem proposed by Huang et al. resistant to chosen-plaintext attack and known-plaintext attack. The modifications in the existing PCS encryption method are proposed to improve its security performance against the potential attacks described above. The Number of Pixel Change Rate (NPCR), Unified Average Changed Intensity (UACI), information entropy, and correlation coefficient analysis are performed to evaluate the statistical performance of the modified PCS method. The simulation analysis reveals that the modified PCS method has better statistical features and is more resistant to attacks than Huang et al.'s PCS method.

Nowadays, various types of attacks are imposed to multimedia during transmission. Also in many applications the security of information is very important. So the information encryption has become an important issue. Many encryption techniques have been proposed to achieve high robustness against different types of attacks and to save information from hackers. In this paper, a new chaotic based optical encryption that depends on Discrete Wavelet Transform (DWT) for image transformation will be introduced for color image encryption. Nine chaotic maps have been used in the proposed technique; eight of them were traditional and one is a new proposed map. As a result of extensive simulation results depending on various performance metrics it has been found that the proposed technique has given better robustness comparing to traditional algorithm.
