In the March of 2006 the IAB held a workshop on the topic of "Unwanted
Internet Traffic". The report from that workshop is documented in RFC
4948 [RFC4948]. Section 8.2 of RFC 4948 calls for [t]ightening the
security of the core routing infrastructure." Four main steps were
identified for improving the security of the routing infrastructure.
One of those steps was "securing the routing protocols' packets on the
wire." One mechanism for securing routing protocol packets on the wire
is the use of per-packet cryptographic message authentication,
providing both peer authentication and message integrity. Many
different routing protocols exist and they employ a range of different
transport subsystems. Therefore there must necessarily be various
methods defined for applying cryptographic authentication to these
varying protocols. Many routing protocols already have some method for
accomplishing cryptographic message authentication. However, in many
cases the existing methods are dated, vulnerable to attack, and/or
employ cryptographic algorithms that have been deprecated. This
document is one of a series concerned with defining a roadmap of
protocol specification work for the use of modern cryptographic
mechanisms and algorithms for message authentication in routing
protocols. In particular, it defines the framework for a key
management protocol that may be used to create and manage session keys
for message authentication and integrity. The overall roadmap reflects
the input of both the security area and routing area in order to form a
jointly agreed upon and prioritized work list for the effort.
