Abstract
One of the most critical aspects of this technologically progressive era is the propagation of information through an unsecured communication channel. The information is electronically transported as binary bits. One of the most important issues in the existing world is the secrecy of these digital contents. In this paper, we used Chebyshev’s polynomial-based, chaotic maps to propose a new technique for encrypting images. The proposed encryption brings confusion as well as diffusion to the system presented, which is one of the utmost essential aspects of the encryption method. The confusion process is performed in two stages, XORing the original image with the Chebyshev polynomial generated matrices and scrambling, the chaotic scrambling matrix is also generated by the Chebyshev polynomial generated matrix, which increases the sensitivity of the cryptosystem to the key which initialize the parameters for Chebyshev polynomial. We checked our planned scheme against various performance analyses and contrasted them with established outcomes. The scheme is accomplished by offering excellent privacy to digital images.
