“After 18 months of evaluation, NIST has selected nine candidates for the third round of the Additional Digital Signatures for the Post-Quantum Cryptography (PQC) Standardization Process. The advancing digital signature algorithms are:

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

NIST Internal Report (IR) 8610 describes the evaluation criteria and selection process. These third-round candidates will have the opportunity to submit updated specifications and implementations (i.e., “tweaks”). NIST will provide more details to the submission teams in a separate message. This third phase of evaluation and review is expected to last approximately two years. […]
