A New Internet-Draft is available from the on-line Internet-Drafts
This draft is a work item of the Routing Area Working Group Working Group of
Title : The Generalized TTL Security Mechanism (GTSM)
Author(s) : V. Gill, et al.
Filename : draft-ietf-rtgwg-rfc3682bis-07.txt
Pages : 14

The use of a packet's Time to Live (TTL) (IPv4) or Hop Limit (IPv6)
to verify whether the packet originated within the same link has been
used in many recent protocols. This document generalizes this
technique. This document obsoletes RFC 3682.
A URL for this Internet-Draft is:
Changes between -06 and -07:
o Be more reserved about multi-hop security properties in section
'Multi-Hop Protocol Sessions'.
o Clarify IP-in-IP tunnel decapsulation/forwarding as decrementing
o Add text on related messages backwards compatibility.
o Editorial updates.
Comments welcome. In particular about new backwards compat text in
section 6.1 Note however that Section 5 (Security Considerations)
has been significantly reworked already, so if you have comments on
that, please hold off.
I'll post a new I-D in a week or two, but if you want to comment right
away, please send them to so that they can be incorporated.
