In recent years there has been a great progress in the application of chaos theory for cryptography. Due to the closeness in characteristics between chaos and cryptography, they together play a dynamic role in designing strong chaos-based security solutions.The major application areas of chaos theory includes many scientific disciplines, mathematics, programming, microbiology, biology, computer science, economics, engineering, finance, philosophy, physics, politics, population dynamics, psychology, robotics, and meteorology. Electroencephalography (EEG) signals contain sensitive health...
