The advent of scalable quantum computing poses existential threats to the cryptographic foundations of secure network communications. This paper presents a comprehensive examination of quantum-resistant (also called post-quantum) cryptographic protocols, their underlying mathematical foundations, the migration challenges for classical networks, and roadmap strategies for next-generation secure communications infrastructure. After framing the threat landscape, we survey major candidate algorithm classes, review standardization activities by National Institute of Standards and Technology (NIST) and other bodies, discuss practical deployment issues in network communications, and propose guidelines for adopting quantum-resistant cryptography in enterprise and infrastructure contexts. The findings emphasize that although full quantum computers capable of breaking current public-key systems may still be some years away, the window for “harvest now, decrypt later” attacks compels early migration planning.
