Analog Chaos-based Secure Communications and Cryptanalysis: A Brief Survey

Zhong Li, Shujun Li, Gonzalo Alvarez, Wolfgang Halang

A large number of analog chaos-based secure communication systems have been proposed since the early 1990s exploiting the technique of chaos synchronization. A brief survey of these chaos-based cryptosystems and of related cryptanalytic results is given. Some recently proposed countermeasures against known attacks are also introduced.
