Using his expertise in theoretical physics, Martin Hasler has helped make sense out of chaos occurring in nonlinear circuits for applications including secure communications. Hasler was among the first researchers to discover that chaos is possible in simple nonlinear circuits. When circuit researchers had viewed the presence of small levels of chaotic behavior in circuits simply as noise that should be eliminated, Hasler demonstrated how chaos can be used to perform technical functions such as the transmission of messages. He showed that such functions rely on synchronizing two circuits, with one circuit encoding information in a transmitted “chaotic message” and the other extracting the information from the chaotic message. He also presented theoretical results and basic system structure for secure chaotic communication applicable to encryption in broadband communication.
An IEEE Life Fellow, Hasler is an Honorary Professor with the École Polytechnique Fédérale de Lausanne, Vaud, Switzerland.
