NIST is pleased to announce the release of Internal Report (IR) 8459, Report on the Block Cipher Modes of Operation in the NIST SP 800-38 Series.
Under the auspices of NIST’s Cryptographic Publication Review Board, IR 8459 supports the ongoing review of the Special Publication (SP) 800-38 series, which approves a variety of block cipher modes of operation for encryption and authentication. In particular, IR 8459 surveys relevant research results about the modes and their implementations, and it provides a set of recommendations to improve the corresponding standards.
