Using the created round keys, the encryption function encrypts the text, and the decryption function decrypts it. 2- The code asks the user to choose an image file in order to encrypt images. The ...
The image data is divided into fixed-size blocks. Each block undergoes the encryption process using the TDES algorithm. The three keys are applied sequentially to each block, providing a layered ...
An image encryption and decryption method of fractional order chaotic systems (FOCS) with predefined time synchronization is proposed in this article. ... system in the decryptor. Let p(t) represent ...
In the past decade, image encryption is given much attention in research of information security and a lot of image encryption algorithms have been introduced. Due to some intrinsic features of images ...
In this paper, we propose a novel 2D hyperchaotic Sine couple map (2D-HSCM) and then the proposed 2D map is analyzed using bifurcation diagrams, attractor trajectory, Lyapunov exponent, fixed point, ...
Second, as the number of images grows, if a SIEA simply encrypts images in serial, the heavy time consumption of encryption will lead to low efficiency of image secure communications [23–29]. Third, ...
