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.
