Chaos-based image encryption using the RSA keys management for an efficient web communication

This paper presents a solution that provides high security for the fast transmission of images through Internet. To reach this goal, a chaos based cryptosystem is implemented using client side and server side technologies. The RSA key pair for encryption and decryption is generated and sent to the server which uses it to encrypt the initial condition and the parameters of the chaotic map. This approach allows us to encrypt the image with the public key and decrypt it only with the private key. Thus the problem of keys management that encounter the chaos-based symmetric cryptosystems is resolved. The proposed method is used to design a suitable web application and the results indicated that our approach provides a fast and secure process for the image transmission.
