A Proposed System for Covert Communication to Distant and Broad Geographical Areas

TL;DR

This paper introduces a covert communication system that embeds messages within Morse code signals transmitted via radio and EchoLink, enabling discreet messaging over large distances and remote locations.

Contribution

It presents a novel method for covert messaging by hiding information in Morse code signals, suitable for remote and broad geographical areas.

Findings

Effective embedding of covert messages in Morse code signals

Communication over long distances using radio and EchoLink

Potential application as an alternative to numbers stations

Abstract

A covert communication system is developed that modulates Morse code characteristics and that delivers its mes- sage economically and to geographically remote areas using radio and EchoLink. Our system allows a covert message to be sent to a receiving individual by hiding it in an existing carrier Morse code message. The carrier need not be sent directly to the receiving person, though the receiver must have access to the signal. Illustratively, we propose that our system may be used as an alternative means of implementing numbers stations.
