Performance Evaluation of Different Chaotic Maps in Chaotic Secure Communication Systems

Using chaotic signals offers several advantages in digital communication systems. One of the most important advantages is increased security which is due to their broad spectrum and noise-like characteristics. In this paper, a chaotic secure communication scheme for chaotic systems is presented. Chaotic modulation and chaotic masking encryptions are combined to find an effective way for chaotic system synchronization and secure communications. The proposed method uses the proportional integral observer (PI- observer) as the receiver from different classes of chaotic systems. Numerical simulations demonstrate the effectiveness of the proposed approach.
