Abstract
Cryptography is a technique used for secure communications or information in the presence of third parties. This work proposes an Image encryption algorithm using the chaotic map. First, this method is produced to generate the secret key using a logistic map. Encryption includes two processes confusion and diffusion and compression is performed using the DWT method. It has compressed the size of the image. The output verified this method has better security performance.
