Journal Article
Ahmad, J., & Hwang, S. O. (2016). A secure image encryption scheme based on chaotic maps and affine transformation. Multimedia Tools and Applications, 75(21), 13951-13976. https://doi.org/10.1007/s11042-015-2973-y

Due to the interesting nonlinear dynamic properties of chaotic maps, recently chaos-based encryption algorithms have gained much attention in cryptographic communities. However, many encryption schemes do not fulfil the minimum key space requirement,... Read More about A secure image encryption scheme based on chaotic maps and affine transformation.

Chaos-based diffusion for highly autocorrelated data in encryption algorithms (2015)
Journal Article

In a single substitution box, the same regions (pixels) of an image are encrypted to one unique symbol. To reduce this type of autocorrelation in data, chaos has been extensively applied over the last decade. By using chaotic maps, a single substitut...

During last few years, transmission of digital multimedia data (images, audios and videos) over Internet, wireless cell phones, television broadcasting etc., has been significantly evolved. The provision of security to store and transmit data with co... Read More about An Experimental Comparison of Chaotic and Non-chaotic Image Encryption Schemes.
