It fixes known problems with the IKE. The way the HASH is currently defined in the {[}RFC-2409{]} does not authen- ticate the ISAKMP {[}RFC-2408{]} packet header, nor does it authenticate any extra ISAKMP payloads inside phase 1 ISAKMP packets. This causes a secu- rity problem when using extra ISAKMP payloads as already defined in the IKE and DOI {[}RFC-2407{]} (vendor ID payload, INITIAL-CONTACT notification etc). There is also suggestion how to fix the Phase 2 authentication hashes so that they will also authenticate the ISAKMP packet header.}, }
