Secure Communication Systems for Modern Military Operations - Foundations, Technologies, and Future Directions

This book offers a comprehensive examination of secure communication systems for modern military operations, addressing the technological and operational challenges of information exchange in contemporary and future battlefields. It traces the evolution of military communications from analog and digital systems to encrypted, software-defined, and AI-enhanced architectures, with emphasis on NATO interoperability, cybersecurity threats, and electronic warfare. Core principles such as signal transmission, encryption, authentication, anti-jamming techniques, and resilient tactical radio networks are analyzed. Advanced topics include secure UAV-to-command center communications, AI-driven routing and spectrum management, satellite systems, 5G/6G military applications, quantum communication, and cognitive radio networks. The book also proposes a future-oriented secure communication framework integrated with C4ISR systems, supported by practical case studies, including the author’s doctoral research. It is intended for researchers, military professionals, engineers, and policymakers seeking resilient and intelligent defense communication solutions.
