Server Name Indication could be encrypted to protect it from being inspected by passive attackers. There are some virtual-hosting type situations where hiding this information is considered desirable.

9 Jul 2019 SNI stands for Server Name Indication and is an extension of the TLS protocol. It indicates which hostname is being contacted by the browser at

Today, according to Akamai, almost 98% of the clients requesting an HTTPS-enabled site support SNI. If the SNI is unencrypted and required to be always present, this scheme will work all the time. The only problem is configuring the SNI -> internal IP mappings in the NAT box. If it's a carrier grade NAT, presumably the carrier will allow configuring wildcard matches against the domain names the customers own. Se hela listan på blog.mozilla.org 2020-03-05 · What is Encrypted SNI? The Server Name Indication (SNI) shares the hostname for outgoing TLS connections in plain-text. Encrypting SNI is another way to secure your web activity from man-in-the-middle (MITM) attacks. Encrypted SNI is enabled by default with the Cloudflare DNS resolver. You should note your current settings before changing anything.

Abstract. This draft describes the general problem of encryption of the Server Name Identification (SNI) parameter.

It is not possible to hide the SNI information if the server requires it to serve the proper certificate. There was discussion on encrypting this information in TLS 1.3. But this idea was abandoned since this would require establishing an additional encryption layer and thus adding additional overhead to the connection establishment.

The purpose of SNI encryption and privacy is to prevent that. Replacing clear text SNI transmission by an encrypted variant will improve the privacy and reliability of TLS connections, but the design of proper SNI encryption solutions is difficult. In the past, there have been multiple attempts at defining SNI encryption. Issues and Requirements for SNI Encryption in TLS draft-ietf-tls-sni-encryption-05. Abstract.

Two most commonly used strategies to avoid this SNI leak-age are domain fronting [21] and omitting SNI [23]. Domain What does the future hold for SNI? The biggest concern over SNI was its scalability. At the outset, some believed that web browsers and servers wouldn’t adopt the technology fast enough.

Consequently, censors can determine the website to which a client is trying to connect via the SNI extension. Two most commonly used strategies to avoid this SNI leak-age are domain fronting [21] and omitting SNI [23]. 2020-02-04 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 SNI is a technology that allows multiple web server to be hosted on the same IP and listening on the same port but use different SSL/TLS certificates for encryption. Before SNI two web servers listening on the same port had to share the certificate, for example having a reverse proxy handling the TLS channel and redirecting the traffic to the actual web-server At first glance, encrypted SNI—in whatever form it may eventually take—is a silver bullet. It's domain fronting without the downsides.
