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.
