FYI OCB is a faster mode for AES than GCM (the current MTI in TLS/1.3). Do read the linked post about how Phil Rogaway intentionally abandoning the OCB patents. ---------- Forwarded message --------- From: Salz, Rich <rsalz=40akamai.com@dmarc.ietf.org> Date: Fri, Feb 26, 2021 at 11:31 AM Subject: [CFRG] OCB patents are abandoned; freely usable To: cfrg@ietf.org <cfrg@ietf.org> Quoting from a posting to the cryptography mailing list, https://www.metzdowd.com/pipermail/cryptography/2021-February/036762.html : On 2/16/21, 9:19 PM, "Jon Callas" <jon@callas.org> wrote: . . . The deal, which is publicly verifiable from the PTO, is that he stopped paying the PTO upkeep fee, and so the patents are all now abandoned. I wrote him because I went to the PTO to check on expiry dates and saw that and thought "huh?" about it. He verified that it was intentional as a way to put the matter to bed without license games. . . . _______________________________________________ CFRG mailing list CFRG@irtf.org https://www.irtf.org/mailman/listinfo/cfrg
