Abstract#R##N#This paper aims to open a new vista of research in the direction of possible application of power electronics DC-DC converters in analog chaotic communication. Most of the work reported on analog chaotic communication is based on the pioneer work of Pecora and Caroll, with synchronization between transmitter and receiver. Receiver based on synchronization, also known as coherent receiver, has a disadvantage of parameter mismatch and is sensitive to noise. In the present work, firstly, a secure transmitter using chaotic DC-DC converters is proposed that encrypts information using chaotic switching map technique. In chaotic switching map technique, the message is encrypted by randomly switching from one chaotic converter to another. The bifurcation parameter of the randomly switched chaotic converter is modulated by the message. Secondly, an attempt has been made to design a robust non-coherent receiver that is adaptable to the switching chaotic transmitters, even in the presence of noise. Once the receiver identifies the chaotic converter, it can decode the message as per the decryption algorithm. With the proposed non-coherent receiver, the disadvantages of coherent receivers can be overcome. We have also devised a prototype smart meter, used in smart distribution grid for implementing the proposed communication technique. Copyright © 2016 John Wiley & Sons, Ltd.
