Study and Realization of a New Color Image and Video Encryption Approach

A new chaotic color image and video encryption algorithm is presented here.The soul of the new algorithm is color image pre-processing before encryption.Chaotic sequences generated by Henon-sine combined chaotic system are used to encrypt the pre-processed matrix with the methods of position shuffling and pixel value substituting.The performance analysis shows that wonderful encryption effect can be performed.The new algorithm,combined with the "single key on one image" technology,is used in video encryption further more. Applicability and excellent performance can be certified by simulation and successful test on the communication platform.
