A Review on Secure Communication Model using Morse Code

This paper introduces the Secure Communication Model (SCM), an innovative IoTbased system designed to facilitate silent communication through the use of laser diodes. The SCM effectively converts text input into Morse code, which is transmitted simultaneously via three lasers, allowing for rapid and reliable communication in environments where audio signals are impractical. By integrating IoT technology with traditional Morse code transmission methods, this model addresses limitations often encountered in conventional systems, such as range and environmental interference. Initial testing results demonstrate high accuracy and efficiency in transmission, establishing SCM as a promising alternative for secure communication. Future enhancements will focus on incorporating cipher techniques to further enhance the security of the transmitted Morse code.
