CMorse—Automated Laser-Based Morse Code Transmission Through Multi-layered Encryption

Abstract

Streamlining and boosting the effectiveness of Morse code communication are a major challenge that limits the application of Morse code in real-life and secure and flawless communication. The main objective of this research is to automate and increase the efficiency of short-range Morse code communication by using multiple laser diodes which allow each message character to be encrypted and transmitted simultaneously in place of the laborious and time-consuming traditional method of Morse communication. In the present approach, message characters are transmitted as a whole, one character at a time instead of a dot (.) or dash (–) at a time. The light rays are projected onto a screen at the transmitter side, and a camera on the descriptor end captures the projected rays and decrypts them using image processing. This reduces the time taken to transmit messages by a significant amount, enabling faster and more reliable Morse communication. Upon entering the desired message on the transmission side, it is encrypted using multiple layers of pangram cryptography. This message is transmitted letter by letter via the Arduino Mega ports onto the screen. The encryption uses a randomized set of pangram keys at each level, making it robust to interceptions and decryption by third parties.
