Abstract - In modern defense operations, securing classified documents and ensuring reliable communication is critical. Traditional military data storage and transmission methods face challenges such as cyber threats, unauthorized access, and data interception. To address these concerns, this research proposes a Secure Wireless Communication for Defense Application (SWCDA), which integrates LoRa (Long Range) technology and a NAS (Network-Attached Storage) server for highly secure, low-power, and long-range data transmission and storage.
The SWCDA system ensures that defense documents are encrypted and stored on a NAS-based satellite server, providing a highly secure and decentralized approach to military data management. This eliminates reliance on terrestrial networks, making the system highly resistant to cyberattacks, data breaches, and network failures. Users can access the stored data only through a dedicated software interface that requires user authentication and credential verification. When a user needs to upload or retrieve a document, they must connect a LoRa module to their device, establishing a secure link with the satellite’s LoRa module for encrypted communication.
Unlike traditional military communication systems, which often suffer from limited range, high power consumption, and vulnerability to jamming, LoRa provides a low-power, long-range, and interference-resistant communication method. The hardware in SWCDA is solely responsible for communication, while encryption, decryption, and access control are managed by the software. This ensures that even if the communication hardware is compromised, the data remains protected through advanced cryptographic mechanisms.
The proposed system is tested under simulated battlefield conditions, evaluating its performance in terms of latency, security, and reliability. Results demonstrate that SWCDA offers a cost-effective, scalable, and highly secure solution for defense communication, ensuring seamless and encrypted data exchange in mission-critical scenarios. This research highlights the architecture, security protocols, and real-world applicability of SWCDA, making it a valuable contribution to modern defense technology
