Ted, Attached is my version of the updated test vectors for appendix A of draft-irtf-cfrg-ocb. The first 16 {N,A,P,C} tuples use incrementing nonces. I added one example with a 96-bit tag and a separate key (since we recommend using a single tag length with any given key). It uses the same nonce as the 128-bit tag example with the same A and P. The final examples use incrementing nonces. I made minor changes to the text. -- James Manger > -----Original Message----- > From: Cfrg [mailto:cfrg-bounces@irtf.org] On Behalf Of Ted Krovetz > Sent: Monday, 27 January 2014 2:11 AM > To: cfrg@irtf.org > Subject: Re: [Cfrg] OCB test vectors reusing nonces > > > > For the above two reasons I think it would be worth updating the test > vectors, despite some risk of causing a slight delay.
