The article is from 2016, but notably OCB mode is no longer patented since 2021.
- brohee 3y agoMy understanding is that one patent is still covering it for a few months : https://patents.google.com/patent/US7949129B2/ https://patents.google.com/patent/US7949129B2/
- upofadown 3y agoPhillip Rogaway explicitly abandoned the OCB patents in 2021: * https://mailarchive.ietf.org/arch/msg/cfrg/qLTveWOdTJcLn4HP3ev-vrj05Vg/ https://mailarchive.ietf.org/arch/msg/cfrg/qLTveWOdTJcLn4HP3... The linked patent reflects the unpaid upkeep fee and shows a status of expired as a result.
