Timeline of scheme data updates and security events tracked on this site.

1. 2026-05-14 Milestone

   NIST announced 9 Round 3 candidates for additional post-quantum signature schemes: FAEST, HAWK, MAYO, MQOM, QR-UOV, SDitH, SNOVA, SQIsign, UOV. Rationale in NIST IR 8610. Round 3 candidates.

   FAEST, HAWK, MAYO, MQOM, QR-UOV, SDitH, SNOVA, SQIsign, UOV

2. 2026-05-09 Attack

   Updated UOV security flags based on pℓ-truncated polynomial ring intersection attack (Furue & Ikematsu, ePrint 2026/298). Improves on Ran's wedge attack for Ip (~128 bits), III (~182 bits), V (~223 bits). Is parameter sets newly flagged as warning (~159 bits, still above threshold).

   UOV

3. 2026-05-09 Attack

   Updated UOV and MAYO security flags based on wedge attack (Ran, ePrint 2025/1143). MAYO-2 ("two") marked broken (~113 bits, below 128-bit threshold). UOV Ip, III, and V parameter sets marked with warning (reduced but still above threshold). UOV Is unaffected.

   UOV, MAYO

4. 2026-05-09 Attack

   Updated SNOVA security flags based on wedge product attack (Bros et al., ePrint 2026/237). 6 parameter sets marked broken: (37 17 2), (25 8 3), (56 25 2), (24 5 5), (75 33 2), (29 6 5). 2 parameter sets marked with warning: (24 5 4), (37 8 4).

   SNOVA

5. 2026-05-08 Update

   Updated 7 schemes to their latest published specifications. PERK redesigned parameter sets (v2.2.0). MQOM adds gf16 variants (v2.1). RYDE and Mirath corrected signature sizes and added faster variants. CROSS, SQIsign, and MAYO updated with revised benchmarks.
