Reviewer: Takeshi Takahashi Review result: Ready I do not see any serious issues on this draft and enjoyed reading it. I have only minor questions for the purpose of deepening my understanding of the draft. 1. In section 5, regarding the The TD-CERT-DIGEST-ALGORITHMS-Data message, who embed the rejectedAlgorithm field? If it will be the KDC, why does the KDC need to fill and distribute this information to the others? 2. In section 8 (security consideration), it is stated that "to do otherwise allows an active attacker to perform a downgrade attack". In my understanding of the draft, arbitrary algorithm could be used (if the negotiation reaches agreements). I wonder if there is any mechanism that discourages the negotiation of using insecure algorithms. For instance, the list of algorithms that must be treated with care could be listed somewhere? Thank you, and kind regards, Take
