I've been working through "Cryptanalysis of OCB2: Attacks on Authenticity and Confidentiality" 1 from earlier this year. My knowledge of OCB2 is pretty shallow though, and so I'm keen to study the scheme in depth before I continue.
From citations and searching around, it seems like OCB2 was introduced in a 2004 paper by Rogaway titled "Efficient instantiations of tweakable blockciphers and refinements to modes OCB and PMAC" 2.
There aren't any explicit mentions of OCB2 in this paper though. Section 10 is titled "The OCB1 Authenticated-Encryption Scheme" and includes a description of "OCB1 with an ideal tweakable blockcipher". The scheme described in that section matches what I have read about OCB2.
I suppose the scheme only started being called OCB2 after the publication of the paper? Is that correct? If not, where can I find a description of OCB2?
