The draft starts by listing known attacks against SNI encryption, and then presents two potential solutions that might mitigate these attacks. 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. Enable SSL. To process SSL traffic, you must enable SSL processing. You can configure SSL based … As SNI encryption becomes common, we can expect more deployment of such "end-to-end" solutions. At the time of this writing, enterprises have the option of installing a firewall performing SNI filtering to prevent connections to certain websites. With SNI encryption, this becomes ineffective.

Regardless of the encryption used, these designs can be broken by a simple replay attack, which works as follow: 1- The user starts a TLS connection to the multiplexed server, including an encrypted SNI value. While a censor can't see what site you're connecting to with ESNI enabled, they can still tell that you're using an encrypted SNI field. If TunnelBear and other anti-censorship tools are the only applications that use ESNI, it's pretty easy for a censor to assume that any traffic using ESNI is attempting to circumvent their system and should be blocked. the establishment of the TLS encryption channel, SNI is sent in cleartext.

The answer is Server Name Indication, or SNI. With SNI the browser, in the initial SSL conversation, advises which site (by name) it wants to access. The server then presents just the required certificate and website content. SNI to the rescue SNI is a weak link in this equation as it’s not encrypted by default.
