■주제: Post Quantum CryptographyQuantum Threat: Preparing for the World Beyond Quantum

■요약: This presentation addresses the quantum threat to modern cryptography and the necessity of transitioning to post-quantum cryptography (PQC). Traditional public-key cryptosystems such as RSA, ECC, and Diffie-Hellman, which rely on the computational hardness of integer factorization and discrete logarithm problems, are vulnerable to Shor's algorithm executable on sufficiently powerful quantum computers. With quantum computers expected to reach practical capabilities within 10-20 years and already demonstrating 1,000+ qubits by 2025, the cryptographic community urgently requires new security standards resistant to quantum attacks. This seminar explores lattice-based cryptography, code-based cryptography, hash-based cryptography, and other emerging cryptographic primitives that form the foundation of NIST-standardized post-quantum algorithms such as Crystals-Kyber, Crystals-Dilithium, Falcon, and SPHINCS+. The presentation provides detailed technical backgrounds on fundamental lattice problems demonstrating how these mathematical hard problems enable quantum-resistant encryption and digital signature schemes to ensure long-term cryptographic security in the post-quantum era.
