1.  Introduction

   [RFC5639] defines new elliptic curve domain parmaeters for curves
   over seven different prime fields, each with a "twisted" varient,
   making a total of fourteen additional domain parameter sets.  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 to numbers.  Other pprotocols, for example
   [IEEE802.11], 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].

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.

   The equation for all elliptic curves defined here is:

      y^2 = x^3 + ax + b (mod p)

   Domain parameter sets consist of:

   o  p: the prime

   o  A, B: parameters to the equation of the curve

   o  x, y: the coordinates of the generator for the group

   o  q: the order of the group formed by the generator

   o  h: the co-factor

   o  z: the "twist" (for twisted curves only)

   The prime used with the twisted curve is the same as its untwisted

   sibling-- that is, brainpoolP256t1 uses "p" from brainpoolP256r1.
   Parameter z is used for the quadratic twist to generate the
   parameters for the twisted varients.  See [EBP] for more information.

3.  IANA Considerations

   IANA is instructed to update the [IANA-IKE] registry entitled "Group
   description" to include the fourteen domain parameter sets defined in
   Section 2 and to add a note for each in the "Note" column of the
   registry saying "not for IKEv1".

4.  Security Considerations

   [EBP] describes the security properties of the curves referenced
   here.  The curves support security levels of 80 (Section 2.1), 112
   (Section 2.3), 128 (Section 2.4), 160 (Section 2.5), and 256
   (Section 2.7).

5.  Insecurity Considerations

   The reason for the note in Section 3 is because [RFC2409] has been
   deprecated but the protocol that deprecated it is not being used in
   any significant fashion and the fear is that using these elliptic
   curves with [RFC2409] will be further disincentive from switching
   over to the new, but seldom used, protocol.

Appendix A.  Appendix A: Test Data

   This section provides some test vectors for example Diffie-Hellman
   key exchanges using each of the curves defined in Section 2.  In all
   of the following sections the following notation is used:

   o  dA: the secret key of party A

   o  x_qA: the x-coordinate of the public key of party A

   o  y_qA: the y-coordinate of the public key of party A

   o  dB: the secret key of party B

   o  x_qB: the x-coordinate of the public key of party B

   o  y_qB: the y-coordinate of the public key of party B

   o  x_Z: the x-coordinate of the shared secret that results from
      completion of the Diffie-Hellman computation

   o  y_Z: the y-coordinate of the shared secret that results from
      completion of the Diffie-Hellman computation
