RSA Algorithm Implementation for Ciphering Medical Imaging

In this paper we will present a software designed for remote visualization of medical images with data security transfer. This interface is implemented under MATLAB environment. The implementation of the image cryptography system uses the RSA algorithm with 64 bits private key length. The transfer of images in a secure way for medical diagnosis is insured by generating a watermarked key to encrypt the original image. More, we introduced a comparison study between the obtained performances and those computed with other algorithms such as DES and IDEA.
