Abstract

In this paper, we design a digital secure communication system based on synchronized random digital sequences (RDSs). For the application to digital secure communication, a novel circuit called the RDS generator (RDSG) is proposed to transfer an analog chaotic signal into a RDS. The digital message is encrypted by the RDS generated from RDSG in the chaotic transmitter via a logical exclusive-OR (XOR) operation and it can be successfully recovered by another synchronized RDS and XOR operation at the receiver. Finally, experimental results demonstrate the success of proposed RDS generators in the secure communication application.
