Locator/ID Separation Protocol (LISP) Data-Plane Confidentiality
Abstract
This document describes a mechanism for encrypting traffic
encapsulated using the Locator/ID Separation Protocol (LISP). The
design describes how key exchange is achieved using existing LISP
control-plane mechanisms as well as how to secure the LISP data plane
from third-party surveillance attacks.

RFC 8061 LISP Data-Plane Confidentiality February 2017
1. Introduction
This document describes a mechanism for encrypting LISP-encapsulated
traffic. The design describes how key exchange is achieved using
existing LISP control-plane mechanisms as well as how to secure the
LISP data plane from third-party surveillance attacks.
The Locator/ID Separation Protocol [RFC6830] defines a set of
functions for routers to exchange information used to map from
non-routable Endpoint Identifiers (EIDs) to routable Routing Locators
(RLOCs). LISP Ingress Tunnel Routers (ITRs) and Proxy Ingress Tunnel
Routers (PITRs) encapsulate packets to Egress Tunnel Routers (ETRs)
and Re-encapsulating Tunnel Routers (RTRs). Packets that arrive at
the ITR or PITR may not be encrypted, which means no protection or
