A new chaotic key-based design for image encryption and decryption

In this paper, an image encryption/decryption algorithm and its VLSI architecture are proposed. According to a chaotic binary sequence, the gray level of each pixel is XORed or XNORed bit-by-bit to one of the two predetermined keys. Its features are as follows: (1) low computational complexity, (2)...

Description
Summary:In this paper, an image encryption/decryption algorithm and its VLSI architecture are proposed. According to a chaotic binary sequence, the gray level of each pixel is XORed or XNORed bit-by-bit to one of the two predetermined keys. Its features are as follows: (1) low computational complexity, (2) high security, and (3) no distortion. In order to implement the algorithm, its VLSI architecture with low hardware cost, high computing speed, and high hardware utilization efficiency is also designed. Moreover, the architecture of integrating the scheme with MPEG2 is proposed. Finally, simulation results are included to demonstrate its effectiveness.
