Synchronization of Chaotic Networks and Secure Communication

Ido Kanter, Wolfgang Kinzel

Research output: Chapter in Book/Report/Conference proceedingChapterpeer-review


Chaotic networks have the potential to be applied for novel secure communication systems. In this regard, synchronization between coupled chaotic lasers is vitally important. This chapter gives an introduction and an overview of chaos synchronization with emphasis on the author’s recent work. For pedagogical reasons, it demonstrates the main results with networks of chaotic Bernoulli units. These results are compared with experiments on semiconductor lasers and with numerical simulations of Lang-Kobayashi equations, which are used to describe chaotic semiconductor lasers. The chapter explains the secure synchronization of two random bit generators with high bandwidth and fidelity over a public channel using a classical mechanism- zero lag synchronization (ZLS) of two mutually coupled chaotic lasers.
