Digital Image Scrambling Method Based on Chaotic Mapping
Zhao Xue-feng · Microelectronics & Computer · 2003
A new method for scrambling digital image in the position space is proposed in this paper,which is based on chaotic mapping.In this method,the piecewise linear mapping is used to generate a chaotic sequence with the key,and the baker's mapping is used to scramble the image matrix with the created sequence.The decrypting operation is the reverse pro-cess of encryption.Experiments show that the proposed algo-rithm has satisfying effect for digital image encryption.
