Announcement

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. 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 Special Publication (SP) 800-131A Revision 2, Transitioning the Use of Cryptographic Algorithms and Key Lengths, is now available for public comment. This revision includes a strategy and schedule for retiring the use of the Triple Data Encryption Algorithm (TDEA). Other proposed changes are listed in Appendix B.
