A New Image Blocking Encryption Arithmetic Based on Chaotic Sequences
Wan Chun · Journal of Jimei University · 2007
A new image encryption algorithm was presented.First,a given initial value and a parameter as password were used to generate a Chaos sequences and its ergodic matrix,and the original image was divided into small blocks of suitable size which were scrambled by the ergodic matrix.Then another given initial value and parameter were used to scramble each of the blocks in the same way.Then the encrypted image was embedded in a suitable image.Experiment results showed that the algorithm was effective and useful.
