A secure chaos-based communication with a Delta-modulated chaotic cryptographic technique is developed in this paper. We prove that a Delta-modulated feedback control of a 1-D discrete- time control system gives rise to a chaotic system. Base on this chaotic system, a modified parameter modulation s...

Zusammenfassung:A secure chaos-based communication with a Delta-modulated chaotic cryptographic technique is developed in this paper. We prove that a Delta-modulated feedback control of a 1-D discrete- time control system gives rise to a chaotic system. Base on this chaotic system, a modified parameter modulation scheme is proposed to improve security. As illustrated by numerical simulation, the parameter in the sender is protected by a secure cryptosystem against two popular attacks.
