                A Survey of Transport Security Protocols
                 draft-ietf-taps-transport-security-02

Abstract

   This document provides a survey of commonly used or notable network
   security protocols, with a focus on how they interact and integrate
   with applications and transport protocols.  Its goal is to supplement
   efforts to define and catalog transport services [RFC8095] by
   describing the interfaces required to add security protocols.  It
   examines Transport Layer Security (TLS), Datagram Transport Layer
   Security (DTLS), Quick UDP Internet Connections with TLS (QUIC +
   TLS), MinimalT, CurveCP, tcpcrypt, Internet Key Exchange with
   Encapsulating Security Protocol (IKEv2 + ESP), SRTP (with DTLS), and
   WireGuard.  This survey is not limited to protocols developed within
   the scope or context of the IETF, and those included represent a
   superset of features a TAPS system may need to support.

Status of This Memo

   This Internet-Draft is submitted in full conformance with the
   provisions of BCP 78 and BCP 79.

   Internet-Drafts are working documents of the Internet Engineering
   Task Force (IETF).  Note that other groups may also distribute
   working documents as Internet-Drafts.  The list of current Internet-
   Drafts is at https://datatracker.ietf.org/drafts/current/.
