A New Internet-Draft is available from the on-line Internet-Drafts directories. This draft is a work item of the IP Security Maintenance and Extensions Working Group of the IETF. Title : Heuristics for Detecting ESP-NULL packets Author(s) : T. Kivinen, D. McDonald Filename : draft-ietf-ipsecme-esp-null-heuristics-01.txt Pages : 33 Date : 2009-09-03
This document describes a heuristic approach for distinguishing ESPNULL (Encapsulating Security Payload without encryption) packets from encrypted ESP packets. The reason for using heuristics instead of modifying ESP is to provide a solution that can be used now without updating all end nodes. With heuristic methods, only the intermediate devices wanting to find ESP-NULL packets need to be updated.
