The Global System for Mobile Communication (GSM) is riddled numerous security flaws, and although it was built with authenticating, signaling confidentiality, and user seclusion as encryption techniques, the GSM channel is still vulnerable to relay, interleaving, and man-in-the-middle attempts. Prior to voice accessing the core network, the GSM communication service is secure. To provide end-to-end security, it is preferable that the GSM subscriber, rather than with the network operator, controls your voice channel's encrypting. At the user's perspective, a new method of encryption is introduced. In this paper, the author uses DSP-Starter-Kit (DSK) to demonstrate our cryptographic techniques on the GSM communication system in real-time. With our technology, the speech is scrambled before it reaches the GSM device, increasing safety and confidentiality. Given that the communicating GSM subscribers' encrypted message is personal to them, the GSM channel will indeed be secret to them. The system's DSK board served as a standalone product that carried out the encryption system. To assess the system's performance in terms of its own performance and latency frequency, real-time tests have been carried out.
