Submit Comments on FIPS 180-4

 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) 180-4
Secure 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

  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

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

NCCoE Releases Draft Project Description for Mitigating AI Bias

Comment Now: NCCoE Draft
Project Description for Mitigating AI Bias 

The National Cybersecurity Center of Excellence (NCCoE) has
released a new draft project description, Mitigating
AI/ML Bias in Context: Establishing Practices for Testing, Evaluation,
Verification, and Validation of AI Systems
. Publication of this
project description begins a process to solicit public comments for the project
requirements, scope, and hardware and software components for use in a
laboratory environment.

We want your feedback on this draft to help refine the project.
The comment period is now open and will close on September 16, 2022.

To tackle the complex problem of mitigating AI bias, this project
will adopt a comprehensive socio-technical approach to testing, evaluation,
verification, and validation (TEVV) of AI systems in context. This approach
will connect the technology to societal values in order to develop guidance for
recommended practices in deploying automated decision-making supported by AI/ML
systems. A small but novel part of this project will be to look at the
interplay between bias and cybersecurity and how they interact with each other.

The initial phase of the project will focus on a proof-of-concept
implementation for credit underwriting decisions in the financial services
sector. We intend to consider other application use cases, such as hiring and
school admissions, in the future. This project will result in a freely
available NIST SP 1800 Series Practice Guide.

Upcoming Workshop Update

Earlier this month, we announced a hybrid workshop on Mitigating AI
Bias in Context on Wednesday, August 31, 2022
. The workshop will now
be virtual only via WebEx and will provide an opportunity to discuss this topic
and work towards finalizing this project description. You can register by
clicking on the above workshop link. We hope to see you there! 

We Want to Hear from You!

The public comment period for this draft is open through September
16, 2022.

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 Signature
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: 

  • Conventional setting: gives
    context of conventional EdDSA/Schnorr-style signature schemes and their
    security properties; 
  • Threshold approaches:
    summarizes various threshold approaches for deterministic and
    probabilistic schemes, at a high level; 
  • Further considerations:
    describes how various aspects only arise in the threshold setting, thus
    requiring a more sophisticated analysis with respect to the security
  • Conclusions: identifies the
    need for additional analysis aided by the community of experts. 

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.

draft. For additional information, see the

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

  • Identify systems dependent on
  • Identify appropriate PNT
  • Detect disturbances and
    manipulation of PNT services
  • Manage the risk to these

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.
