Image Encryption Algorithm Based on Combined Multi-Dimension Chaotic System
Yang De-gang · Journal of Jiangxi Normal University · 2010
An image encryption algorithm based on combined multi-dimension chaotic system is proposed.Initial permutation mechanism is introduced in this algorithm,which can enhance its security.In the meantime,diffusion mechanism is introduced in encryption process,this measure can enhance resistance to plain-chosen attacks.Theoretic analysis and simulations prove that this scheme has enough key space and can defend brute-force attacks.For encrypted image is high sensitive to initial key and the values of adjacent pixels satisfy zero correlation,so this encryption system is of relatively high security.
