2 NIST Algorithm Families

The candidate cryptosystems submitted to NIST's post-quantum standardization project — lattice-based key encapsulation and symmetric-primitive signatures.

FrodoKEM
A conservative, unstructured-lattice key-encapsulation mechanism. A NIST Round 3 alternate, now standardized by ISO and recommended by BSI and ENISA.
Lattice-based KEM
Picnic
A post-quantum digital signature family built from zero-knowledge proofs and symmetric-key primitives rather than number-theoretic hardness assumptions.
Signature scheme
qTESLA
A Ring Learning-With-Errors signature scheme from a multi-university collaboration. Submitted to NIST Round 2; link updated here to Microsoft Research's project page.
