Abstract:With the popularity of the Internet, the transmission of images has become more frequent. It is of great significance to study efficient and secure image encryption algorithms. Based on traditional Logistic maps and consideration of delay, we propose a new one-dimensional (1D) delay and linearly coupled Logistic chaotic map (DLCL) in this paper. Time delay is a common phenomenon in various complex systems in nature, and it will greatly change the dynamic characteristics of the system. The map is analyzed in terms of trajectory, Lyapunov exponent (LE) and Permutation entropy (PE). The results show that this map has wide chaotic range, better ergodicity and larger maximum LE in comparison with some existing chaotic maps. A new method of color image encryption is put forward based on DLCL. In proposed encryption algorithm, after various analysis, it has good encryption performance, and the key used for scrambling is related to the original image. It is illustrated by simulation results that the ciphered images have good pseudo randomness through our method. The proposed encryption algorithm has large key space and can effectively resist differential attack and chosen plaintext attack.

“…In literature, enormous effort has been made on the data security applications via optical approach. This is because, optics possesses multi-dimensional nature and parallel processing of large storage data, which can be carried out at higher speeds [9].The double random phase encoding (DRPE) technique is the classical optical encryption scheme which has been implemented in different transform domains in order to enhance the security, including FRT [10], Fresnel transform [11], WT [12,13]. As a generalization of the WT, the fractional wavelet transform (FWT) has been applied in information security [14].…”

In order to trade-off between computational effects and computational cost of present image encryption algorithm, a novel image encryption algorithm based on lifting-based wavelet transform is proposed in this paper. The image encryption process includes three steps: first the original image was divided into blocks, which were transformed by lifting based wavelet; secondly the wavelet domain coefficients were encryption by random mask which generated by user key, and finally employing Arnold scrambling to encrypt the coefficients. The security of proposed scheme is depended on the levels of wavelet transform, user key, and the times of Arnold scrambling. Theoretical analysis and experimental results demonstrate that the algorithm is favorable. Keywords-information security; image encryption; fractional Fourier transform; random phase mask; blockbased transformation.I.
