A Digital Image Encryption Algorithm Based on Chaotic Sequences
Fei Gao · Telecommunication Engineering · 2006
Some improvement is presented for producing the chaotic sequence based on Logistic mapping.The method overcomes the disadvantage of short period which usually appears with one dimension chaos system.Further more,the new chaotic sequence takes on better random statistical property.A JPEG digital image encryption algorithm is proposed based on chaotic sequences above,which is implemented during image compression.Encryption image according to this method takes on quite compression efficiency.Experimental results show that encryption effect is satisfactory.
