In August 2021, NIST’s Crypto Publication Review Board initiated a review process for NIST Special Publication (SP) 800-107 Rev. 1, Recommendation for Applications Using Approved Hash Algorithms. Public comments are compiled here.
NIST proposes to withdraw SP 800-107 Rev.1.
Public comments on this decision proposal may be submitted to cryptopubreviewboard@nist.gov by July 30, 2022.
Rationale for the proposed decision
SP 800-107 Rev. 1 discusses the security strengths of hash functions and provides recommendations on digital signatures, HMAC, hash-based key derivation functions, random number generation, and the truncation of hash functions.
Since the publication of SP 800-107 Rev. 1 in 2012, NIST published (or revised) multiple recommendations that cover hash functions in different applications in more detail (e.g., SP 800-90, SP 800-106, SP 800-56A/B/C, SP 800-131A, SP 800-133, SP 800-135). In order to keep requirements of a specific use of a primitive on a single standard and to simplify the management of our standards, the board proposed withdrawing SP 800-107 Rev. 1. Requirements listed in SP 800-107 Rev.1 that are not currently addressed in other standards will be moved to the relevant publication when it is updated.
