Abstract
In this paper, we introduce a novel chaos-based image encryption scheme. We perform our scheme using both the binary form and decimal form of chaotic maps. We also use two chaotic maps; one generates the initial values of the other. Thus, we utilize the best two properties of chaos ergodicity and sensitivity to the initial value. We increase the security of the cipher by introducing a reverse order round to resist cryptanalysis attacks.
Highlights
In recent years, the transmission of digital images over communication media has developed greatly
Its idea is to generate from one initial condition several chaotic initial conditions by the first chaotic map, e.g., Logistic map, for another chaotic map, e.g., PWLCM
Let us begin with the key design and introduce the encryption process and decryption process to recover the plain image
Summary
The transmission of digital images over communication media has developed greatly. We use the resultant chaotic sequences of the second map in both forms, the binary form and the real number form, and apply it to diffuse and confuse the image. Let us begin with the key design and introduce the encryption process and decryption process to recover the plain image.
