In this article we propose the use of a Liouvillian chaotic system on a master–slave scheme for secure communications. Two forms of data encryption are presented, the first is a state observer based on the Super-Twisting algorithm, the second is a receiver designed through the properties of Liouvillian systems, this last receiver does not suffer from data loss due to synchronization error present...
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...
