        The Transport Layer Security (TLS) Protocol Version 1.3
                        draft-ietf-tls-tls13-03

Abstract

   This document specifies Version 1.3 of the Transport Layer Security
   (TLS) protocol.  The TLS protocol provides communications security
   over the Internet.  The protocol allows client/server applications to
   communicate in a way that is designed to prevent eavesdropping,
   tampering, or message forgery.
