    Brainpool Elliptic Curves for the IKE Group Description Registry
                 draft-harkins-brainpool-ike-groups-03

Abstract

   This memo allocates code points for four new elliptic curve domain
   parameter sets over finite prime fields into a registry that was
   established by The Internet Key Exchange (IKE) but is used by other
   protocols.

Internet-Draft    Brainpool ECC for IKE Group Registry     December 2012

1.  Introduction

   [RFC5639] defines new elliptic curve domain parmaeters for curves
   over a number of different prime fields, each with a "twisted"
   varient.  These curves have a number of interesting security
   properties (as described in [EBP]) that make them desirable to use.

   IANA maintains a registry for [RFC2409] to map complete domain
   parameter sets into easily-referenced numbers.  While [RFC2409] is
   deprecated, other protocols, for example [IEEE802.11] and [RFC5931],
   refer to this registry for its convenience.  Therefore, this memo
   instructs IANA to allocate new code points for the Brainpool curves
   defined in [RFC5639] to the registry established by [RFC2409] to be
   used by other protocols.

1.1.  Requirements Language

   The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT",
   "SHOULD", "SHOULD NOT", "RECOMMENDED", "MAY", and "OPTIONAL" in this
   document are to be interpreted as described in RFC 2119 [RFC2119].

2.  Brainpool Elliptic Curves

   [RFC5639] defines several elliptic curves over finite prime fields
   (ECP, in the parlance of [RFC2409]).  The domain parameter sets for
   each of the elliptic curves defined in [RFC5639] and are copied here
   for convenient reference.
