Memristor based Chaotic Circuit Design for Secure Communication

摘要

From the early pre-historic ages communication has been a major element of human evolution. From gesture to the imitation of natural sounds, ever since the necessity of communication was realized by humans, it has taken various forms. The importance of security in communication, however, was not given a thought until recent eighty's. The first few secure communication models were designed during world war-I. The implementation of security in communication back then was limited to military purposes only. Later, when the growth of technology allowed common people to use electronic communication gadgets, the necessity of security was fully realized. Now that we have a wide complexity of communication happening across the globe every second, security becomes the sole priority. Undoubtedly there are hundreds of ways of establishing secure communication, security still is a matter to be updated. Chaos in electronics is one such area which can be used to establish secure communication. Due to its unpredictability, it becomes one of the most secure communication models. In this paper, we design a memristor-based chaotic circuit which can be used to establish secure communication. We analyze the stability of the model and prove that the chaotic signal generator with memristor can be used for real-time secure communication. Further, we design a PSPICE model of the device which, due to the presence of memristor will be self-correcting in nature.
