Academic paper: QUANTUM CRYPTOGRAPHY AND POST-QUANTUM SECURITY: CURRENT STATE, CHALLENGES, AND STRATEGIC DIRECTION

A November 2025 academic paper warns that current cryptographic systems face imminent threats from quantum computing advancements, with Shor’s algorithm capable of breaking RSA and ECC encryption within a decade. Researchers highlight Quantum Key Distribution (QKD) as the most mature quantum-safe solution, though deployment remains limited by high costs and infrastructure gaps in global networks. The study identifies post-quantum cryptography (PQC) standardization as critical, with NIST’s selected algorithms (e.g., CRYSTALS-Kyber) gaining traction but requiring faster adoption to outpace quantum decryption risks. Challenges include scalability issues in quantum networks, hardware vulnerabilities in early-stage quantum processors, and the need for hybrid classical-quantum security frameworks during the transition period. Strategic recommendations urge governments and enterprises to prioritize PQC migration, invest in quantum-resistant infrastructure, and foster public-private collaborations to mitigate the looming "crypto-apocalypse.".
