NIST vydal Special Publication 800-38F, Recommendation for Block Cipher Modes of Operation: Methods for Key Wrapping

22.12.2012
This publication describes cryptographic methods for the protection of the confidentiality and integrity of cryptographic keys. In addition to clarifying that some previously-approved methods are permitted for key wrapping, this publication specifies two deterministic authenticated-encryption modes of operation of the Advanced Encryption Standard (AES) algorithm: the AES Key Wrap (KW) mode and the AES Key Wrap With Padding (KWP) mode. An analogue of KW, called TKW, with the Triple Data Encryption Algorithm (TDEA) as the underlying block cipher, is also specified to support legacy applications.
