A secure color image encryption based on 3D-hyperchaotic logistic map.

Image encryption has become an important issue and a new field in image processing. The Hyperchaotic image encryption scheme has advantages that make it more robust against attacks, faster encryption speed, and easy to implement. In this study, a Novel cryptographic algorithm (a new hyperchaotic map) can be utilized for color image encryption with differing formats presentation through high levels of security and efficiency. By using Hyperchaotic Image Encryption, Hyper Logistic (HIEHL), a secure image transfer method can develop. Due to the wide range of hyperchaos, our 3D-Logistic map is more ergodic and unpredictable than the Lyapunov exponent. An encryption scheme based on 3D-Logistic maps is developing to protect color images by substituting pixels in multiple directions. A chaotic sequence separates adjacent pixels from their correlations, resulting in a change in pixel value. The scheme has been tested on different color images and is effective against various threats, image encryption (HIEHL), and data loss. [ABSTRACT FROM AUTHOR]
