TLS session resumption makes it obsolete to perform the key exchange via DH/RSA, and the calculation of the master_secret (but the key expansion has still to be performed). We simplified the description in this blog article to make it easier to understand.

TLS Session Resumption: Full-speed and Secure Feb 24, 2015 We need to talk about Session Tickets - Filippo.io Sep 28, 2017 Postfix TLS Support When the TLS handshake fails for an opportunistic TLS session, rather than give up on mail delivery, the Postfix SMTP client retries the transaction with TLS disabled. Trying an unencrypted connection makes it possible to deliver mail to sites with non-interoperable server TLS implementations.

Methods to prevent session hijacking include: Encryption of the data traffic passed between the parties by using SSL/TLS; in particular the session key (though ideally all traffic for the entire session). This technique is widely relied-upon by web-based banks and other e-commerce services, because it completely prevents sniffing-style attacks.

EMS TLS extension enforcement causing capacity issue In ADC Transport Layer Security (TLS) protocol for any mechanism that relies on the master secret for authentication, an example being session resumption. To prevent against any vulnerabilities for “man-in-the-middle” attack, in the October 2019 patch, Microsoft enabled the EMS extension by default for all Microsoft clients and servers.

TLS Session Resumption: Full-speed and Secure

TLS 1.3 Session Resumption In previous protocols, the client and server sides each maintained a session ID cache. When a client attempted to reestablish a previous connection, its cache was queried to obtain the session ID to put into the initial handshake message. When the server received the session ID, it queried its own cache to determine RFC 5077 - Transport Layer Security (TLS) Session RFC 5077 Stateless TLS Session Resumption January 2008 alternate way to distribute a ticket and use the TLS extension in this document to resume the session. This behavior is beyond the scope of the document and would need to be described in a separate specification. 3.1.Overview The client indicates that it supports this mechanism by including a SessionTicket TLS extension in the ClientHello What is a TLS/SSL certificate, and how does it work?
