Parallel distributed compensation scheme for chaotic masking system via Rivest cipher 4 stream cipher

This study presents a design methodology for Takagi-Sugeno (T-S) fuzzy models-based secure communications in multiple time-delay chaotic (MTDC) systems with Rivest cipher 4 (RC4) algorithm. The main advantage of the RC4 algorithm is that key length does not affect encryption and decryption speeds. To block hacker from stealing message, this proposes increasing complexity an encrypted message (ciphertext) using method double masking. As result, more system can effectively defend (ciphertext). First, are used to encrypt initial (plaintext). enhance security, then converted into signal, which Additionally, improved genetic (IGA) adopted study, it seek better feedback gains controllers speed up synchronization. In accordance IGA, model-based controller synthesized exponentially stabilize error so trajectories slave approach those master systems. Finally, numerical example simulations provided illustrate effectiveness proposed method.
