Hi Paul,

https://github.com/lake-wg/edhoc/pull/442

Is a PR to the traces draft with invalid test vectors. The work before focused more or less only on valid test vectors. I wish we had looked at this earlier, but I think it very good that we did now.


https://github.com/lake-wg/edhoc/pull/446

Is my collection of things that are not optimal in the EDHOC draft. These were found during the work on invalid traces. The PR contains two things:

1. Sender side and wire format: Minor clarifications and corrections on encoding. These are editorial thing that I intend to bring up in my AUTH48 review. I just did this part of my AUTH48 review early.

2. Receiver side: Some suggested changes to what a receiver does with various types of invalid encoding. This would involve changes to RFC2119 words and therefore goes beyond clarification and corrections and I therefore send it to the WG. I think the topic of what to do with different types of invalid messages was ignored a bit. These changes do not change the requirements on the sender or the wire format at all.

I think the current text on when to abort invalid messages is not optimal. On the otherhand it is things that are 100% in the receiver implementations and does not affect the sender or the wire format. While changes would be good it is not 100% essential, a receiver implementation can do this anyway. I don't know what "pause the publication process" would mean. These changes would clearly need consensus in the WG, but I don’t know what the exact process would be. I assume that is partly up to the AD.

Cheers,
John

The plan is to:
- include the traces PR in the next version of the draft.
- include the EDHOC PR duing AUTH48.

No PRs should be merged during AUTH48.

Are you talking about the edhoc draft or the edhoc-traces draft ?

We can pause the publication process if needed.
