Title: IMAGE ENCRYPTION BASED ON STRANGE ATTRACTOR
Authors: Jirí Giesl and Karel Vlcek
Abstract: Chaotic systems are extremely sensitive to initial conditions and this feature can be very helpful in the field of cryptography. Various encryption schemes use chaotic systems for encryption key generation and this key is then used for pixel permutation and pixel diffusion. But chaotic systems and their maps can be used directly for encryption purpose. Proposed scheme is based on extended map of Clifford strange attractor, where each dimension has specific role in the encryption process. Two dimensions are used for pixel permutation and the third dimension is used for pixel diffusion. The theoretical and simulation results prove many properties of this scheme such as large key space and high security.
Keywords: image encryption, chaos encryption, strange attractors, chaotic maps, image security analysis.
