  Chaotic cryptography describes the use of chaos theory (in particular
physical dynamical systems working in chaotic regime as part of communication
techniques and computation algorithms) to perform different cryptographic tasks
in a cryptographic system. In the end, the question is, can chaotic systems
provide alternative techniques able to enhance cryptographic algorithms?. This
chapter can be a worthy material to guide the reader in order to answer himself
this question. Thus, the objective of this chapter is to give a general vision
of what chaotic cryptography is and a comprehensive example that illustrates
the main techniques used in this field.
