Rijndael is famous for its high security and efficiency.According to the characters in the digital image field,there are huge data and high redundancy and strong relativity between the pixels,this paper uses Key Addition,S-boxShiftRows,MixColumns of Rijndael in the digital image encryption field,puts forward an image scrambling algorithm of based on the Rijndael.It completes transformation of image pixel,substitution of image pixel and re-arrangment of image pixel.The results show that: the encrypted image is similarly the white noise,to gain the good scrambling degree.
