A Survey on Hybrid Cryptographic Frameworks Combining Post-Quantum and Classical Techniques

This record contains the full-text survey paper titled “A Survey on Hybrid Cryptographic Frameworks Combining Post-Quantum and Classical Techniques.” The paper systematically reviews hybrid cryptographic frameworks that combine classical public-key techniques with NIST-standardized post-quantum cryptographic primitives such as CRYSTALS-Kyber and Dilithium. It analyzes representative studies across secure communication protocols, blockchain systems, and performance benchmarking to evaluate security, efficiency, and deployment feasibility. The survey highlights hybrid cryptography as a practical migration strategy against the “Harvest Now, Decrypt Later” threat, discusses key trade-offs, and identifies open research challenges for real-world post-quantum adoption.
