Issues and Requirements for SNI Encryption in TLS
Internet Draft describes the general problem of encrypting the
Server Name Indication (
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.
Encrypted Server Name Indication is an attempt to make that happen.
