Abstract

Real time secured system for analog voice communications device has been designed and implementation to avoid eavesdropping on transmitted voice signals, the securing system based on Hybrid method Combines between Encryption by XOR and Voice Random scrambling methods. Arduino boards are used in the transmitted and received stages. In transmitted stage, the sound signal converted from analog to a digital form. The digital data is encrypted by XOR method then stored in Arduino board. The memory of Arduino board is divided into a different random section to achieve voice Random-scrambling methods. Then, the digital storage data sound converted to new analog signal (quietly deference from original voice signal) and transmitted by a communication device. The same procedure is retried in received stage to remove the both of scrambling and XOR encryption procedure in order to retrieval of the original sound signals.
