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 BlackBerry 10 smartphone on the Verizon Wireless 4G LTE network. Original Message From: Aaron Zauner Sent: Wednesday, August 5, 2015 17:17 To: TLS Mailing List Subject: Re: [TLS] AES-OCB in TLS [New Version Notification for draft-zauner-tls-aes-ocb-03.txt] 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/?submit=draft&id=draft-zauner-tls-aes-ocb Specifically.. Rogaway: https://datatracker.ietf.org/ipr/2640/ IBM: https://datatracker.ietf.org/ipr/2647/ The current document is available on the IETF website, I've made a few minor editorial changes in my git repository [0] but not yet uploaded a new version of the document as I'm still waiting if people would like to see more substantial changes to the document. I'd be happy to receive feedback on the document and am looking forward for people to try out AES-OCB in TLS (an upcoming OpenSSL version will ship with default-support I am told). Thanks for your patience, Aaron [0] https://github.com/azet/draft-zauner-tls-aes-ocb/commits/master
