+Abstract
+
+   This document defines new Modular Exponential (MODP) Groups for the
+   Internet Key Exchange (IKE) protocol.  It documents the well known
+   and used 1536 bit group 5, and also defines new 2048, 3072, 4096,
+   6144, and 8192 bit Diffie-Hellman groups numbered starting at 14.
+   The selection of the primes for theses groups follows the criteria
+   established by Richard Schroeppel.

+RFC 3526           MODP Diffie-Hellman groups for IKE           May 2003
+
+
+1.  Introduction
+
+   One of the important protocol parameters negotiated by Internet Key
+   Exchange (IKE) [RFC-2409] is the Diffie-Hellman "group" that will be
+   used for certain cryptographic operations.  IKE currently defines 4
+   groups.  These groups are approximately as strong as a symmetric key
+   of 70-80 bits.
+
+   The new Advanced Encryption Standard (AES) cipher [AES], which has
+   more strength, needs stronger groups.  For the 128-bit AES we need
+   about a 3200-bit group [Orman01].  The 192 and 256-bit keys would
+   need groups that are about 8000 and 15400 bits respectively.  Another
+   source [RSA13] [Rousseau00] estimates that the security equivalent
+   key size for the 192-bit symmetric cipher is 2500 bits instead of
+   8000 bits, and the equivalent key size 256-bit symmetric cipher is
+   4200 bits instead of 15400 bits.
+
+   Because of this disagreement, we just specify different groups
+   without specifying which group should be used with 128, 192 or 256-
+   bit AES.  With current hardware groups bigger than 8192-bits being
+   too slow for practical use, this document does not provide any groups
+   bigger than 8192-bits.
+
+   The exponent size used in the Diffie-Hellman must be selected so that
+   it matches other parts of the system.  It should not be the weakest
+   link in the security system.  It should have double the entropy of
+   the strength of the entire system, i.e., if you use a group whose
+   strength is 128 bits, you must use more than 256 bits of randomness
+   in the exponent used in the Diffie-Hellman calculation.

+RFC 3526           MODP Diffie-Hellman groups for IKE           May 2003
+
+
+2.  1536-bit MODP Group
+
+   The 1536 bit MODP group has been used for the implementations for
+   quite a long time, but was not defined in RFC 2409 (IKE).
+   Implementations have been using group 5 to designate this group, we
+   standardize that practice here.
+
+   The prime is: 2^1536 - 2^1472 - 1 + 2^64 * { [2^1406 pi] + 741804 }
+
+   Its hexadecimal value is:
+
+      FFFFFFFF FFFFFFFF C90FDAA2 2168C234 C4C6628B 80DC1CD1

+
+   The generator is: 2.
+
+3.  2048-bit MODP Group
+
+   This group is assigned id 14.

+
+8.  Security Considerations
+
+   This document describes new stronger groups to be used in IKE.  The
+   strengths of the groups defined here are always estimates and there
+   are as many methods to estimate them as there are cryptographers.
+   For the strength estimates below we took the both ends of the scale
+   so the actual strength estimate is likely between the two numbers
+   given here.

+9.  IANA Considerations
+
+   IKE [RFC-2409] defines 4 Diffie-Hellman Groups, numbered 1 through 4.
+
+   This document defines a new group 5, and new groups from 14 to 18.
+   Requests for additional assignment are via "IETF Consensus" as
+   defined in RFC 2434 [RFC-2434].  Specifically, new groups are
+   expected to be documented in a Standards Track RFC.
