Novel method of chaotic systems evaluation for implementations of encryption algorithms

Many papers reporting microelectronic chaos based applications have appeared in recent years. The focus of cryptology has been mainly on the algorithm implementation rather than on the chaotic system choice. In this paper, a novel method is proposed which aims at properly selecting a chaotic system to be used with encryption algorithms. The properties directly related to the algorithm strength and implementation complexity are the parameters that guide the system choice. Six chaotic systems have been examined with a summary of the data for quick design application made available.
