How NIST Is Securing The Quantum Era

This article argues for urgent development of post-quantum cryptography, outlines NIST’s multi-round PQC standardization effort (beginning 2016 and targeting draft standards in the 2022–2024 timeframe), and describes Infineon’s contributions and proof-of-concept implementations—notably New Hope (a lattice-based KEM) and SPHINCS+ (a hash-based signature)—alongside discussion of candidate signature and KEM algorithms, mathematical problem classes, and related EU/German research projects.
