Title : Issues and Requirements for SNI Encryption in TLS
Authors : Christian Huitema
Eric Rescorla
Filename : draft-ietf-tls-sni-encryption-07.txt
Pages : 14
Date : 2019-09-24
Abstract:
This draft 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. The draft lists known
attacks against SNI encryption, discusses the current "co-tenancy
fronting" 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.
