Abstract

A secure chaos-based communication with a-modulated chaotic cryptographic technique is developed in this paper. We prove that a -modulated feedback control of a 1-D discretetime 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.
