NIST requests comments on IR 8214B initial public draft: Notes on Threshold EdDSA/Schnorr Signatures

NIST requests public comments on the initial public draft (ipd) of NIST IR 8214B, Notes on Threshold EdDSA/Schnorr Signatures. This report considers signature schemes that are compatible with the verification phase of the Edwards Curve Digital Signature Algorithm (EdDSA) specified in Draft Federal Information Processing Standards (FIPS) publication 186-5. The report analyzes threshold schemes, where the private signing key is secret-shared across multiple parties, and signatures can be produced without the parties reconstructing the key. Security holds even if up to a threshold number of parties has been compromised.

The report reviews the properties of EdDSA/Schnorr deterministic and probabilistic signatures schemes, both in the conventional (non-threshold) and threshold setting, summarizing various known properties and approaches. These threshold signatures can allow for a drop-in replacement of conventional signatures without changing the legacy code used for verification. This work is useful to advance the NIST Multi-Party Threshold Cryptography project, which is also interested in other primitives. The document suggests that it is beneficial to further consult with the community of experts for security formulations, technical descriptions, and reference implementations. 

The report includes a section for each of the following: 

The public comment period is open through October 24, 2022. See the publication details for a copy of the draft and instructions for submitting comments.

Open for Public Comment: Zero Trust Architecture Preliminary Draft Practice Guide (Vol. C-D)

The Zero Trust Architecture (ZTA) team at NIST’s National Cybersecurity Center of Excellence (NCCoE) invites public comments on volumes C-D of a preliminary draft practice guide “Implementing a Zero Trust Architecture”. This guide summarizes how the NCCoE and its collaborators are using commercially available technology to build interoperable, open standards-based ZTA example implementations that align to the concepts and principles in NIST Special Publication (SP) 800-207, Zero Trust Architecture. As the project progresses, the preliminary draft will be updated, and additional volumes will also be released for comment.

As an enterprise’s data and resources have become distributed across the on-premises environment and multiple clouds, protecting them has become increasingly challenging. Many users need access from anywhere, at any time, from any device. The NCCoE is addressing these challenges by collaborating with industry participants to demonstrate several approaches to a zero trust architecture applied to a conventional, general purpose enterprise IT infrastructure on premises and in the cloud.

We Want to Hear from You!

The NCCoE is making volumes C-D available as a preliminary draft for public comment while work continues on the project. Review the preliminary draft and submit comments online on or before September 9, 2022.

Foundational PNT Profile: Applying the Cybersecurity Framework for the Responsible Use of Positioning, Navigation, and Timing (PNT) Services.

The PNT cybersecurity profile is part of NIST’s response to the February 12, 2020, Executive Order (EO) 13905, Strengthening National Resilience Through Responsible Use of Positioning, Navigation, and Timing Services. The EO notes that “the widespread adoption of PNT services means disruption or manipulation of these services could adversely affect U.S. national and economic security. To strengthen national resilience, the Federal Government must foster the responsible use of PNT services by critical infrastructure owners and operators.” The Order also calls for updates to the profile every two years or on an as needed basis.

Based on NIST’s interaction with public and private sector stakeholders and their efforts to create “sector specific” profiles, it was decided to create Revision 1. No substantive changes were made to the original Foundational Profile; NIST is only seeking comments on the changes made in this Revision. Among the most noteworthy are: the addition of five new Cybersecurity Framework (CSF) Subcategories, and the addition of two appendices; Appendix D; Applying the PNT Profile to Cybersecurity Risk Management, and Appendix E; Organization Specific PNT Profiles.

All changes are captured in Table 26: “Change Log” for easy reference to reviewers.

The PNT Profile was created by applying the NIST CSF to help organizations:

Organizations may continue to use this profile as a starting point to apply their own unique mission, business environment, and technologies to create or refine a security program that will include the responsible use of PNT services.

NIST Releases Draft IR 8409: Measuring the Common Vulnerability Scoring System Base Score Equation

 Today, NIST is seeking public comments on NIST IR 8409 ipd (initial public draft), Measuring the Common Vulnerability Scoring System Base Score Equation.

Calculating the severity of information technology vulnerabilities is important for prioritizing vulnerability remediation and helping to understand the risk of a vulnerability. The Common Vulnerability Scoring System (CVSS) is a widely used approach to evaluating properties that lead to a successful attack and the effects of a successful exploitation. CVSS is managed under the auspices of the Forum of Incident Response and Security Teams (FIRST) and is maintained by the CVSS Special Interest Group (SIG). Unfortunately, ground truth upon which to base the CVSS measurements has not been available. Thus, CVSS SIG incident response experts maintain the equations by leveraging CVSS SIG human expert opinion.

This work evaluates the accuracy of the CVSS “base score” equations and shows that they represent the CVSS maintainers' expert opinion to the extent described by these measurements. NIST requests feedback on the approach, the significance of the results, and any CVSS measurements that should have been conducted but were not included within the initial scope of this work. Finally, NIST requests comments on sources of data that could provide ground truth for these types of measurements.

The public comment review period for this draft is open through July 29, 2022. See the publication details for instructions on how to submit comments.

NIST Requests Public Comments on FIPS 180-4, Secure Hash Standard (SHS)

 NIST is in the process of a periodic review and maintenance of its cryptography standards and guidelines.   

This announcement initiates the review of Federal Information Processing Standard (FIPS) 180-4Secure Hash Standard (SHS), 2015.

NIST requests public comments on all aspects of FIPS 180-4. Additionally, NIST would appreciate feedback on the following two areas of particular concern:

  1. SHA-1. In recent years, the cryptanalytic attacks on the SHA-1 hash function have become increasingly severe and practical (see, e.g., the 2020 paper "SHA-1 is a Shambles" by Leurent and Peyrin). NIST, therefore, plans to remove SHA-1 from a revision of FIPS 180-4 and to deprecate and eventually disallow all uses of SHA-1. The Cryptographic Module Validation Program will establish a validation transition schedule.

     *  How will this plan impact fielded and planned SHA-1 implementations?

     *  What should NIST consider in establishing the timeline for disallowing SHA-1?

  1. Interface. The "Init, Update, Final" interface was part of the SHA-3 Competition submission requirements. Should a revision of FIPS 180-4 discuss the “Init, Update, Final” hash function interface?

 The public comment period is open through September 9, 2022. Comments may address the concerns raised in this announcement or other issues around security, implementation, clarity, risk, or relevance to current applications.  

Send comments to cryptopubreviewboard@nist.gov with “Comments on FIPS 180-4” in the Subject.

Using Business Impact Analysis to Inform Risk Prioritization and Response: NIST IR 8286D available for public comment

 Traditional business impact analyses (BIAs) have been successfully used for business continuity and disaster recovery (BC/DR) by triaging damaged infrastructure recovery actions that are primarily based on the duration and cost of system outages (i.e., availability compromise). However, BIA analyses can be easily expanded to consider other cyber-risk compromises and remedies.

This initial public draft of NIST IR 8286D, Using Business Impact Analysis to Inform Risk Prioritization and Response, provides comprehensive asset confidentiality and integrity impact analyses to accurately identify and manage asset risk propagation from system to organization and from organization to enterprise, which in turn better informs Enterprise Risk Management deliberations. This document adds expanded BIA protocols to inform risk prioritization and response by quantifying the organizational impact and enterprise consequences of compromised IT Assets.

The public comment period for this draft is open through July 18, 2022. See the publication details for a copy of the draft and instructions for submitting comments.
