NIST’s Crypto Publications Review: Block Cipher Modes of Operation: Status Update (G11c)

The Crypto Publication Review Board was established by NIST to identify cryptography standards and other publications to be reviewed. Currently, the NIST-recommended modes of operation (NIST SP 800-38 Series) are undergoing review.
At this type of writing, the Crypto Publication Review Project website (https://csrc.nist.gov/Projects/crypto-publication-review-project) lists the following modes of operation as subject to review: SP 800-38A (ECB, CBC, CFB, OFB, CTR), SP 800-38A Addendum (three ciphertext stealing variants for CBC), SP 800-38D (GCM and GMAC), and SP 800-38E (XTS).
This talk will give a technical overview of the NIST-recommended modes of operation that are subject to review, giving insights into the functionality of the algorithms, and an overview of the public comments received. It is expected that when ICMC 2022 will be held in September 2022, NIST will have made some announcements related to the review of these modes of operation. This gives an opportunity to provide a status update, and to collect feedback for NIST from the ICMC 2022 participants.
