Abstract :
Commercial cipher SMS4 symmetric algorithm is applied to design one image encryption and decryption system to perform the function of image encryption and decryption and improve the safety of image transmission and storage and thus effectively protect digital image contents. Test result indicates that pixel gray levels of encrypted image are more equally distributed and image information is effectively concealed with better encryption effects and enhanced image security.
