So now that OCB is finally free, do we want to implement it? :)

I'm honestly not sure if the improvements of AES-GCM are worth it.
I haven't heard of vulnerabilities in IKE/ESP wrt. IVs or counters.

Subject: [Cryptography] Direct public confirmation from Dr. Rogaway


https://mailarchive.ietf.org/arch/msg/cfrg/qLTveWOdTJcLn4HP3ev-vrj05Vg/ :

 

I can confirm that I have abandoned all OCB patents

and placed into the public domain all OCB-related IP of mine.

While I have been telling people this for quite some time, I don't

think I ever made a proper announcement to the CFRG or on the

OCB webpage. Consider that done.

 

I hope people will use the scheme to do positive things.
