Exploring the foundations of lattice-based cryptography

This blog post introduces lattice-based cryptography as a quantum-resistant foundation for post-quantum security, contrasting it with RSA/ECC, outlining core hard problems (LWE, SIS, SVP, CVP), and summarizing NIST-selected algorithms (ML-KEM/Kyber, ML-DSA/Dilithium, FN-DSA/FALCON) for key encapsulation and digital signatures; it highlights advantages such as quantum resistance, scalability, and crypto agility, and describes government, commercial, and IoT applications, while promoting Sectigo’s certificate management and post-quantum readiness offerings.
