Quantum Shield: Cyber Sovereignty and Military Communications in the Post-Quantum Era

The rapid advancement of quantum computing has rendered the cryptographic foundations of modern secure communications increasingly vulnerable. This is not a future threat; it is an operational reality demanding immediate institutional response. Quantum Shield Offers a comprehensive technical, strategic, and institutional framework for navigating the quantum transition. Drawing on post-quantum cryptography standardization (NIST FIPS 203-206), defense architecture, and digital sovereignty policy, the book addresses the full spectrum Of the challenge: from the mathematical hardness assumptions underlying PQC algorithms to the geopolitical dynamics of cryptographic independence and military interoperability. Written for security engineers, policy-makers, military and intelligence professionals, and researchers, Quantum Shield is both a technical reference and a strategic guide for institutions that cannot afford to be unprepared.
