An 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 کاملAn Improved Image Encryption Algorithm based on Chaotic System
The security of stream cipher, which is known as one of the main cipher techniques, is dependents completely on the quality of generated pseudo-stochastic sequences. Chaotic systems can produce the pseudo-random sequences with good randomness , therefore, these systems are suitable to the stream cipher. In this paper, a new encryption algorithm is proposed by analyzing the principle of the chao...

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...
