An Image Encryption Technique based on Chaotic S-Box and Arnold Transform
In recent years, chaos has been extensively used in cryptographic systems. In this regard, one dimensional chaotic maps gained increased attention because of their intrinsic simplicity and ease in application. Many image encryption algorithms that are based on chaotic substitution boxes (S-boxes) have been studied in the last few years but some of them appear to be vulnerable to robustness. We,...
متن کاملColor Image Encryption using 3D Chaotic Map with AES key Dependent S-Box
Techniques in encrypting digital images play a crucial role in the prevention of unauthorized access. This paper focuses on color image encryption and decryption using 3D chaotic map with AES key dependent S-Boxes. It contains four major parts which are Exclusive X-or forward and backward, 3D Logistic Map, 3D Chebyshev map, and 2D Arnold Cat Map, and Dynamic S-box of AES. Here, Exclusive X-or i...
متن کاملA Secure Iris Image Encryption Technique Using Bio-Chaotic Algorithm
Due to dramatic enhancement in computers and communications and due to huge use of electronic media, security gains more and more importance especially in those organizations where information is more critical and more important. The older techniques such as conventional cryptography use encryption keys, which are long bit strings and are very hard to memorize such a long random numbers. Also i...
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...
متن کاملImage Encryption Based on Improved Chaotic Sequences
Image encryption is an active and challenging research area. This article proposes a transposing and scrambling image encryption algorithm based on improved hyper-chaotic sequence to provide enhanced security for encrypted image transmission. The algorithm processes the hyper-chaotic sequence according to the pixel information, which makes the keys be sensitive to original image. Then we apply ...
