Transitioning the Use of Cryptographic Algorithms and Key Lengths: NIST Seeks Comments on Draft SP 800-131A Rev. 2
July 19, 2018

NIST is updating its guidance for transitioning to the use of stronger cryptographic keys and more robust algorithms by federal agencies to protect sensitive, but unclassified, information. This is the second update to NIST Special Publication (SP) 800-131A, Transitioning the Use of Cryptographic Algorithms and Key Lengths, since its initial publication in 2011. These transitions are meant to address the challenges posed by new cryptanalysis, the increasing power of classical computing technology, and the potential emergence of quantum computers.

Draft SP 800-131A Revision 2 is now available for public comment. This revision includes a strategy and schedule for retiring the use of the Triple Data Encryption Algorithm (TDEA) specified in SP 800-67, Recommendation for the Triple Data Encryption Algorithm (TDEA) Block Cipher. Other proposed changes are listed in Appendix B.

Please provide comments by September 7, 2018 to, with "SP 800-131A comments" in the subject line.
