Hi Filippo,
* Indeed, if the SCADA industry has a particular need, they should profile TLS for use in that industry, and not require we change the recommendation for the open Internet. We have an IoT profile for TLS and it talks about the use of PSK, see https://tools.ietf.org/html/rfc7925 On the "open Internet" (probably referring to the Web usage) you are not going to use PSKs in TLS. There is a separate RFC that provides recommendations for that environmnent, see RFC 752. That RFC is currently being revised, see draft-sheffer-uta-rfc7525bis-00<https://datatracker.ietf.org/doc/draft-sheffer-uta-rfc7525bis/> Ciao Hannes IMPORTANT NOTICE: The contents of this email and any attachments are confidential and may also be privileged.
