A Improvement for Chaotic Image Cryptosystem Based on Skew Tent Map
BO Lu-yu · Journal of Nanjing University of Posts and Telecommunications · 2011
A new chaotic cryptosystem based on skew tent map was proposed by making use of a mixed chaotic sequences,which are produced by combining the dynamic encryption parameter and a simple single-dimensional chaotic map.The simulation result shows the proposed cryptosystem inherited the advantages of the original one and it shows that the proposed algorithm greatly enhances the security of image encryption without image distortion comparing with the traditional skew tent map chaotic encryption algorithm.
