Image encryption using chaotic logistic map
In recent years, the chaos based cryptographic algorithms have suggested some new and efficient ways to develop secure image encryption techniques. In this communication,wepropose a newapproach for image encryption basedon chaotic logisticmaps in order tomeet the requirements of the secure image transfer. In the proposed image encryption scheme, an external secret key of 80-bit and two chaotic ...
متن کاملCryptanalyzing 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...
متن کاملImage 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...
متن کاملEncryption of Image Using Chaotic Map
The advent of internet has paved the way for transmitting more and more information over the internet in a very less time and multimedia technology is also not untouched with it. Audio, images & other multimedia are being transmitted over the internet. The traditional encryption schemes appear not to be ideal for image applications, due to some intrinsic features of images such as bulk data cap...
متن کاملCryptanalyzing 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.
