Image 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 کاملCryptanalysis of Image Encryption Scheme Based on Chaotic Tent Map
With the development of chaos theory, many image encryption algorithmshave been designed using the properties associated withthechaotic map. The chaotic map shows high sensitivity to initial conditions and the sequence generated using chaotic map are unpredictable making it a good choice for performing encryption operation. But, without proper encryption algorithm design, encryption scheme desi...
متن کاملAn Image Encryption Scheme Based on 2D Tent Map and Coupled Map Lattice
This paper proposes a chaos-based image encryption scheme where one 2D tent map with two control parameters is utilized to generate chaotic orbits applied to scramble the pixel positions while one coupled map lattice is employed to yield random gray value sequences to change the gray values so as to enhance the security. Experimental results are carried out with detailed analysis to demonstrate...
متن کاملA Chaos-based Image Encryption Scheme Using 3D Skew Tent Map and Coupled Map Lattice
This paper proposes a chaos-based image encryption scheme where one 3D skew tent map with three control parameters is utilized to generate chaotic orbits applied to scramble the pixel positions while one coupled map lattice is employed to yield random gray value sequences to change the gray values so as to enhance the security. Experimental results have been carried out with detailed analysis t...
متن کاملComments on an image encryption scheme based on a chaotic Tent map
Recently an image encryption scheme based on a chaotic Tent map has been proposed by Li et al. [1]. This comment shows that this scheme is broken and no secure application can be found for it. The recent paper by Li et al. [1] proposed a chaotic image encryption based on a Tent map and evaluated its security through statistical analyses. It is true that when an image encryption scheme is design...
