Encryption 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 کاملImage 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 کاملImage encryption based on chaotic tent map in time and frequency domains
The present paper is aimed at introducing a new algorithm for image encryption using chaotic tent maps and the desired key image. This algorithm consists of two parts, the first of which works in the frequency domain and the second, in the time domain. In the frequency domain, a desired key image is used, and a random number is generated, using the chaotic tent map, in order to change the phase...
