A Digital Image Encryption Algorithm of High Security
Fei Yao-ping · Microelectronics & Computer · 2007
In this paper,a new digital image encryption algorithm of high security is proposed.This algorithm overcomes the disadvantages of Arnold and else which is not security.The security of this algorithm is determined by the length of the key for it's transformation controlled by the key.Experimental results show that this algorithm has the advantages of fast transformation and easy inversion.It is only several times for this algorithm to get a good scrambling effect which has good practical value in information hiding and digital watermarking.A new method is proposed for estimating how is the digital image is scrambled.
