Enhanced Cryptography by Multiple Chaotic Dynamics

Enhanced Cryptography by Multiple Chaotic Dynamics

A potential security vulnerability of embedding compression in a chaos-based cryptography is studied. Furthermore, a scheme for improving its security is proposed. This correspondence considers the use of multiple chaotic dynamics and drive chaotic trajectory by both plaintext sequence and initial v...

Chaotic trajectory is used for encryption that is never reused for different plaintext. This makes that scheme naturally resist chosen plaintext attack and cipher text-only attack.
