An Image-Encipherment Algorithm Using a Combination of a One-Dimensional Chaotic Map and a Three-Dimensional Piecewise Chaotic Map

An Improved Piecewise Linear Chaotic Map Based Image Encryption Algorithm

An image encryption algorithm based on improved piecewise linear chaotic map (MPWLCM) model was proposed. The algorithm uses the MPWLCM to permute and diffuse plain image simultaneously. Due to the sensitivity to initial key values, system parameters, and ergodicity in chaotic system, two pseudorandom sequences are designed and used in the processes of permutation and diffusion. The order of pr...

Image encryption using the two-dimensional logistic chaotic map

Chaos maps and chaotic systems have been proved to be useful and effective for cryptography. In this paper, the two-dimensional logistic map with complicated basin structures and attractors are first used for image encryption. The proposed method adopts the classic framework of the permutation-substitution network in cryptography and thus ensures both confusion and diffusion properties for a se...

A New Image Encryption Algorithm Based on Two- dimensional Coupled Chaotic Map

In this paper, a kind of two-dimensional coupled chaotic transcendental map (TCCTM) was proposed. Firstly, by using the TCCTM chaotic sequences were generated,then the chaotic sequences were modified to generate chaotic key stream that is more suitable for image encryption. In the process of encryption, an original color image was decomposed into three images of red, green and blue components, ...

Three-Dimensional Image of A Communicating Uterus

Recent advances in reproductive medicine have created a demand for more accurate and safe imaging modalities before assisted reproductive treatment(ART) (1). Gradually, the important role of three-dimensional (3D) ultrasonography in the diagnosis of uterine congenital anomalies has been proved (2-4).
