With the rapid and progressive development of medical images and data exchange in digital formats, information security and image encryption are becoming more important in data storage and transmission. Because of the widespread use of medical images in hospitals and healthcare communities, it is important to protect them from unauthorized access. In this paper, we propose a medical image encryption algorithm based on a chaotic technique. A chaotic logistic map is used to scramble the pixel values of a medical image. In order to achieve a high level of security, a simplified version of the Data Encryption Standard (DES) is used. In order to verify the higher level of security and performance with the proposed algorithm, an experiment analysis has been performed.
