NIST First Call for Multi-Party Threshold Schemes

Date Published: January 25, 2023

NIST requests public comments on NIST IR 8214C ipd (initial public draft), NIST First Call for Multi-Party Threshold Schemes, for primitives organized into two categories:

  1. Cat1: selected NIST-specified primitives
  2. Cat2: other primitives not specified by NIST

The report specifies the various categories, subcategories, and requirements for a successful submission, including security characterization, technical description, open-source implementation, and performance evaluation. The process intends to help the NIST cryptographic technology group collect reference material to promote a public analysis of the viability of threshold schemes and related primitives. This will support the NIST multi-party threshold cryptography and privacy-enhancing cryptography projects in developing future recommendations.

Threshold schemes should NOT be submitted until the final version of this report is published. However, using the present draft as a baseline, potential submitters are encouraged to prepare early for future submissions.

The public comment period is open through April 10, 2023. Public comments to be considered for the final report should be submitted by email to We encourage you to use this comment template when preparing your feedback comments. Proper comments will later be compiled and made publicly available along with the final version of this report.

For announcements and discussion of NIST’s Multi-Party Threshold Cryptography project, please join the MPTC-forum.

NOTE: A call for patent claims is included on page iii of this draft. For additional information, see the Information Technology Laboratory (ITL) Patent Policy – Inclusion of Patents in ITL Publications.
