When responding, please keep the subject line intact and reply to all email addresses included in the To and CC lines. (Feel free to cut this introductory paragraph, however.)

The document, along with other ballot positions, can be found here: https://datatracker.ietf.org/doc/draft-ietf-trill-over-ip/ ---------------------------------------------------------------------- COMMENT: ---------------------------------------------------------------------- Based on my conversation with DEE, I understand that the HMAC is always computed over a value which is disjoint with the HKDF-Label. This is not really cryptographically ideal -- as I stated in my review, you should be HKDFing two keys off the same key -- but it does imply that the trivial attack doesn't work, so I'm removing my DISCUSS. As we discussed, please add some explanation of why this is a non-issue to the document. _______________________________________________ trill mailing list [email protected] https://www.ietf.org/mailman/listinfo/trill
