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 کاملNew Algorithm for Color Image Encryption Using Improved 1D Logistic Chaotic Map
This paper introduces a simple and effective improved one-dimension (1D) Logistic chaotic map. Simulations and performance evaluations show that the improved 1D Logistic chaotic map is able to get larger chaotic range and better chaotic behaviors compared with its prototype map. To investigate its applications in multimedia security, I propose an efficient encryption algorithm for color image. ...
متن کاملAn Improved Image Encryption Scheme Using Chaotic Logistic Maps
Chaos theory has significantly contributed towards the development of fast and secure image encryption algorithms. Authors in [1] proposed an efficient and secure approach for image encryption based on chaotic logistic maps. The algorithm uses an 80-bit secret key and two chaotic logistic maps, whose initial conditions are derived using the secret key. Depending upon the outcome of logistic map...
متن کاملAn Improved Piecewise Linear Chaotic Map Based Image Encryption Algorithm
An image encryption algorithm based on improved piecewise linear chaotic map (MPWLCM) model was proposed. The algorithm uses the MPWLCM to permute and diffuse plain image simultaneously. Due to the sensitivity to initial key values, system parameters, and ergodicity in chaotic system, two pseudorandom sequences are designed and used in the processes of permutation and diffusion. The order of pr...
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...
