Re: [sfc] TR: New Version Notification for draft-rebo-sfc-nsh-integrity-01.txt

Hi, 

I agree that integrity protection is important, and I'd like to support this work. 

In addition to encryption of metadata, I assume that a mechanism to prevent accidentally errors on metadata would be also needed.  For example, it may be realized by integrating some error correction mechanism into NSH scheme, or defining a rule for a case that an SF/SF proxy detects metadata error is detected (e.g., delete the errored metadata, discard whole of packet).

Best regards,

Shunsuke

Thank you for your work on this Med and Tiru.
Working Group, this is a topic we have in the charter, and explicitly 
told the IESG we would work on.  Please review and comment on the 
approach described here.

Thank you,
Joel (as co-chair)
