[Stackevo] draft-hardie-path-signals and draft-trammell-wire-image

["Brian Trammell (IETF)" <[e-mail]>]

Greetings,

After discussion at our Friday morning London meeting (and thanks, all, on the program for your remarkable  Stack Evolution Program would like the IAB to consider two documents for publication on the IAB stream:

https://tools.ietf.org/html/draft-trammell-wire-image-03

https://tools.ietf.org/html/draft-hardie-path-signals-03

The wire image draft describes what a protocol's wire image is, and explores the situations that arise when a protocol splits its visible wire image from the information it uses for its own operation. (It started as a draft I wrote during the extended Singapore plenary discussion on encryption of protocols, riffing off Ted's observation from the dais that protocols with explicit wire images were a completely new thing, in part to describe what I mean when I use the term.)

The path signals draft recommends that protocol machinery be confidentiality protected, and that any signal exposed to on-path devices (outside confidentiality protection) be *explicitly* so exposed and integrity protected. It reiterates that metadata injection is considered harmful.

Thanks, cheers,

Brian (stackevo lead hat)
