TLS Abbreviated Handshake

Overview#

TLS Abbreviated Handshake looks like this:#

Client (with SessionID)                              Server

 ClientHello                  -------->
                                ServerHello (with SessionID)
                                          [ChangeCipherSpec]
                              <--------      ServerHelloDone
 [ChangeCipherSpec]
 Finished                     -------->
 Application Data             <------->     Application Data

TLS Session Resumption#

TLS Session Resumption [1] is one of the most important mechanism to improve TLS Handshake performance: by submitting an appropriate blob to the server, a client is able to trigger an abbreviated handshake, improving latency and computation time.
