standardization of additional signature schemes
summary
NIST opens an on‑ramp for additional signature standards and receives 50 submissions, of which 40 are accepted into the first round across multivariate (many UOV), MPC‑in‑the‑head, lattice (7), code‑based (6), symmetric (4), isogeny (1) and others. Early cryptanalysis already yields several broken candidates, some parameter rescalings and implementation fixes. Process cuts to a smaller pool in months, expects multiple rounds, and plans to standardize at most one or two new signatures that complement — not replace — Dilithium; test vectors for existing PQC algorithms are already published.
