               Network Performance Measurement for IPsec
                        draft-ietf-ippm-ipsec-02

Abstract

   The O/TWAMP security mechanism requires that endpoints (i.e. both the
   client and the server) possess a shared secret.  Since the currently-
   standardized O/TWAMP security mechanism only supports a pre-shared
   key mode, large scale deployment of O/TWAMP is hindered
   significantly.  At the same time, recent trends point to wider IKEv2
   deployment, which in turn calls for mechanisms and methods that
   enable tunnel end-users, as well as operators, to measure one-way and
   two-way network performance in a standardized manner.  This document
   discusses the use of keys derived from an IKE SA as the shared key in
   O/TWAMP.  If the shared key can be derived from the IKE SA, O/TWAMP
   can support cert-based key exchange, which would allow for more
   flexibility and efficiency.  Such key derivation can also facilitate
   automatic key management.

1.  Introduction

   The One-way Active Measurement Protocol (OWAMP) [RFC4656] and the
   Two-Way Active Measurement Protocol (TWAMP) [RFC5357] can be used to
   measure network performance parameters, such as latency, bandwidth,
   and packet loss by sending probe packets and monitoring their
   experience in the network.  In order to guarantee the accuracy of
   network measurement results, security aspects must be considered.
   Otherwise, attacks may occur and the authenticity of the measurement
   results may be violated.  For example, if no protection is provided,
   an adversary in the middle may modify packet timestamps, thus
   altering the measurement results.
