Cryptanalyzing a nonlinear chaotic algorithm (NCA) for image encryption

This paper describes the security weakness of a recently proposed image encryption algorithm based on a logistic-like new chaotic map. We show that the chaotic map’s distribution is far from ideal, thus making it a bad candidate as a pseudo-random stream generator. As a consequence, the images encrypted with this algorithm are shown to be breakable through different attacks of variable complexity.

Cryptanalyzing an image encryption scheme based on logistic map

Chaotic behavior arising from very simple non-linear dynamical equation of logistic map makes it was used often in designing chaotic image encryption schemes. However, some properties of chaotic maps can also facilitate cryptanalysis especially when they are implemented in digital domain. Utilizing stable distribution of the chaotic states generated by iterating the logistic map, this paper pre...

Cryptanalysis on an Image Scrambling Encryption Scheme Based on Pixel Bit

Recently, an image scrambling encryption algorithm which makes use of one-dimensional chaos system for shuffling the pixel bits was proposed in [G.-D. Ye, Pattern Recognition Lett. 31(2010) 347-354]. Through the scrambling algorithm, the pixel locations and values can be encrypted at the same time. This scheme can be thought of as a typical binary image scrambling encryption considering the bit...

Image Encryption using Curved Scrambling and Diffusion

In the recent world, designing of a secure cryptosystem is prime focused area for the researchers. This paper emphasizes on the image encryption/decryption technique using a key derived from a plain image. In the proposed algorithm, encryption key is derived by applying new curved scrambling method to the RGB layers of a plain image. In next step, a temporary cipher image is obtained by modulo ...
