Abstract: Natural disasters are on a rise all over the world, and these have pointed out vulnerabilities in existing Public Warning Systems, which fail during crises when they become choked with information, and it is not very efficient for people using basic mobile technology. The standard Short Message Service is widely accepted and in practice but lacks basic authentication, which makes this service a highly vulnerable target for Denial of Service (DoS) attacks and message spoofing attacks. This research proposes a Disaster Alert System with an advanced Cryptographic Security system over SMS notifications for authenticated and safe transfer of information. The major highlight is a security system capable of functioning under resource-constrained systems. The system utilizes a robust 4096-bit key and RSA/ECDSA encryption methods for providing a high level of integrity. This solution has proved to be resilient under simulated critical disaster situations in terms of latency performance in encryption speed. The system has undergone thorough testing and proved to possess strong reliability and stability. Furthermore, this system can be deployed with relative ease, which confirms scalability capabilities in covering a country-wide warning system. This research successfully tackled the SMS security vulnerability to present a secure and efficient model which can transform the conventional Short Message Service into a reliable public warning service platform.
