Alan, thank you for your review! We had not thought about the collisions of uft8-username within the realm. After some discussion, the best solution seemst to be to let the server assign a full NAI instead of just the Realm. This is the only significant change made to the new draft 3. Tuomas

I understand the issues that have been discussed: (1) feature completeness of the specification, (2) availability of implementations, and (3) compactness of the binary encoding. We initially, in 2016, considered ASN.1, CBOR and JSON as equal candidates and rejected CBOR because the

Hi Philip, It would definitely be useful to provision various types of long-term credentials after the security bootstrapping and to use them for reauthentication later. One way to achieve this with the current spec is to use the exported AMSK as a shared key for a separate credential

I was looking at the EAP-TLS with TLS 1.3 draft and noticed that it forbids PSK authentication. Why is that? While there is the EAP-PSK method, I would much rather use EAP-TLS with PSK because it provides identity protection and perfect forward secrecy, unlike EAP-PSK. In fact, I think

Yes, the new Realm assigned in the Initial Exchange should be used already during the Waiting Exchange and Completion Exchange. As part of the editorial improvements in draft-06, I edited the specification to be clearer on this point. The reason is better compatibility with roaming

Thank you for bringing up this issue. If there is broader demand for NIST P-256, we certainly can consider adding it to the draft. In any case, it would make sense to have two different curves in the specification to facilitate interoperability testing of the cryptosuite negotiation. At this

Hi Eduardo, 1. I' not sure what kind of alternative key derivation you are suggesting. Are you thinking about alternative ECDH curves, or RSA maybe? I believe even the low-end devices can do ECDHE these days so it is not obvious to me why that should be sometimes avoided. 2. This is a valid
