At IETF 106, we discussed forming a design team to focus on external PSK management and usage for TLS. The goal of this team would be to produce a document that discusses considerations for using external PSKs, privacy concerns (and possible mitigations) for stable identities, and more developed mitigations for deployment problems such as Selfie. If you have an interest in participating on this design team, please reply to this message and state so by 2359 UTC 31 January 2020.

Cheers,

Joe and Sean
