WebApr 24, 2024 · AES algorithm is implemented using the MATLAB platform. Here image is taken as input, applying the AES encryption algorithm creates a cipher mage and this cipher image is input to the decryption algorithm which reconstructs the original image back. Result for camera man image is as shown below. Input image. WebAug 14, 2024 · A wide variety of cryptographic algorithms for images have been proposed in the literature. Kuo [1] proposed an image encryption method known as image distortion which obtains the encrypted image by adding the phase spectra of the plain image with those of the key image. This method is safe but no image compression is considered.

WebThe Caesar cipher (or Caesar code) is a monoalphabetic substitution cipher, where each letter is replaced by another letter located a little further in the alphabet (therefore shifted but always the same for given cipher message). The shift distance is chosen by a number called the offset, which can be right (A to B) or left (B to A). WebNov 12, 2024 · Image encryption is an effective method for protecting private images during communication, and many image encryption methods have been proposed [ 1 – 3 ]. Chaos is famous for its sensitivity to initial conditions and system parameters, pseudorandomness, ergodicity and reproduction. It is suitable for image encryption.
