Hi Janfred,
thanks for the review again.
We meanwhile have submitted a new version as quoted below which hopefully addresses your comments.
Thanks again and 
Viele Grüße/Best regards
Dirk

A new version of I-D, draft-hsothers-iotsens-ps-03.txt has been successfully submitted by Dirk von Hugo and posted to the IETF repository.

Name:		draft-hsothers-iotsens-ps
Revision:	03
Title:		The Need for New Authentication Methods for Internet of Things
Document date:	2022-11-04
Group:		Individual Submission
Pages:		11
URL:            https://www.ietf.org/archive/id/draft-hsothers-iotsens-ps-03.txt
Status:         https://datatracker.ietf.org/doc/draft-hsothers-iotsens-ps/
Htmlized:       https://datatracker.ietf.org/doc/html/draft-hsothers-iotsens-ps

Abstract:
   In framework of future 6G the need for easy and secure connectivity
   between a great amount of small devices as sensors and household
   appliances will be essential.  Such massive Internet of Things (mIoT)
   requires authentication methods which are reliable also in case of
   vulnerable wireless links and work for simple cheap (dumb) devices.

   Aim of this document is to lay ground for the need for new
   authentication models and admission methods in the framework of
   devices (e.g., machines in IoT communication) within a (wireless or
   wireline-based) network.

   Simple devices may only have a minimum amount of physical interfaces
   available.  As an example for establishing an out-of-band channel for
   exchange of authentication material radio sensing technology may
   serve.  This is currently under investigation for Wireless LAN and
   upcoming cellular radio at both IEEE and 3GPP.

This text is great.
I think it gives a very clear and concise explanation of the objective of the draft and is easy to read.

Maybe BRSKI as a way of zero-touch-Provisioning can still be a part of the draft, but then it would be good to explain what challenges BRSKI brings in the current use case.

Since BRSKI is designed especially to provision devices without need to manually configure them, someone may ask why you can't use BRSKI to reach your goal.

Unfortunally, I'm not a BRSKI expert, but maybe I can try to suggest a short text for a BRSKI section in the next few weeks (most likely not before the IETF in London, my schedule is quite full for the next weeks).

Good to hear it was helpful :)

I'm looking forward to the new draft version.
