Aaron, Great work! I can't wait to see OCB standardized and implemented. One thing though. There has been mentioning of Gligor patent(s) - were you able to look into that? Or perhaps Phil or Charanjit could comment on this (though technical people seldom make legal statements :)? Sent from my

Hi, A short update on the matter of IPR related to AES-OCB in TLS: It took some time but over the past couple of weeks all IPR exemptions have been filed by the original patent holders (Rogaway and IBM [Jutla]). These IPR exemptions can be viewed over here: https://datatracker.ietf.org/ipr/search

Christer, do agree of course. But independent of the RFC 5764 correction, below clarification proposal for rtcweb-transport remains valid (“due to the sharing assumption”). Regards, Albrecht From: Christer Holmberg [mailto:christer.holmb...@ericsson.com] Sent: Mittwoch, 5. August 2015 10:13 To:
