A new Request for Comments is now available in online RFC libraries. RFC 8744 Title: Issues and Requirements for Server Name Identification (SNI) Encryption in TLS Author: C. Huitema Status: Informational Stream: IETF Date: July 2020 Mailbox: huitema@huitema.net Pages: 13 Updates/Obsoletes/SeeAlso: None I-D Tag: draft-ietf-tls-sni-encryption-09.txt URL: https://www.rfc-editor.org/info/rfc8744 DOI: 10.17487/RFC8744 This document describes the general problem of encrypting the Server Name Identification (SNI) TLS parameter. The proposed solutions hide a hidden service behind a fronting service, only disclosing the SNI of the fronting service to external observers. This document lists known attacks against SNI encryption, discusses the current "HTTP co-tenancy" solution, and presents requirements for future TLS-layer solutions. In practice, it may well be that no solution can meet every requirement and that practical solutions will have to make some compromises.
