                    Name Identification (SNI) Encryption in TLS

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.

This document is a product of the Transport Layer Security Working Group of the IETF.
