• In this paper we propose the use of chaotic systems on a master-slave scheme for secure communications. This cryptosystem allows to use the advantages of block cyphers in color images, these features permits us to encrypt messages as large as images without the need of keys bigger than the transmitted data, this is achieved by using the synchronization of two chaotic oscillators and fractals such as Julia sets. Two different receivers will be presented; the first one is an exponential polynomial observer and the second is a reconstruction of the states based on the properties of Liouvillian systems, the latter retaining the same security features but with a more simple implementation and faster encryption and decryption times.
