Technical Summary
This draft describes the general problem of encryption of the Server
Name Identification (SNI) 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.
Working Group Summary
Some working group members are not in favor of encrypting the SNI. However,
the working group has consensus for continued work on the general topic of SNI encryption.
Document Quality
