Re: [Perc] I-D Action: draft-ietf-perc-private-media-framework-08.txt

Hi,

This version is much better than 07. Thanks for the work on that. I think it’s now ready for IETF Last Call. I will request that shortly.

I have a few new minor editorial comments that can be addressed along with any IETF LC feedback.

Thanks!

Ben.

- (Nit) §1, 2nd paragraph:  The new text addresses my concern, but it added a comma splice. I suggest making the text starting with "this draft aims…” into its own sentence.

The text was removed. I assume the authors decided it was not specific to PERC?

- (Nit) §4.5.2, 3rd paragraph:

 The change resolves my concern, but I have one editorial suggestion:

OLD:
When a Key Distributor decides to re-key a conference, it transmits a new EKTKey message [
I-D.ietf-perc-srtp-ekt-diet  to each of the conference participants containing the new EKT Key.
NEW:
When a Key Distributor decides to re-key a conference, it transmits a new EKTKey message
containing the new EKT Key [I-D.ietf-perc-srtp-ekt-diet] to each of the conference participants.

- (Nit): New §6.1: "While the number key types is very small”
s:/“number key types”/“number of key types"
