Carlson Filename : draft-ietf-pppext-lbd-03.txt Pages : 5 Date : 29-Jun-01 The Point-to-Point Protocol (PPP) [1] provides a standard method for transporting multi-protocol datagrams over point-to-point links. PPP also defines an extensible Link Control Protocol (LCP), that allows the detection of optional link handling procedures, and a Multilink procedure (MP) [2], that allows operation over multiple parallel links. This document defines an extension to MP called Link Balancing Detection (LBD) and the LCP options that control this extension. This extension allows high-speed implementations to use the single-NCP negotiation model of MP without requiring the cost associated with the unneeded MP datagram buffering and reordering.

Getting good! A few comments, though: 1. It focuses a bit too much on PPP and its associated protocols (ECP). I guess other implementations (such as 802.1x) and associated protocols (WEP...) should be at least mentionned. 2. The new lightweight challange is nice, but I still have a problem with the link/EAP endpoint separation when using AAA. In the case of a remote AAA server, the reauth should probably be end-to-end (AAA server to EAP client), not on the local link (this enables a home server to ensure that the user is still connected and that the local NAS/AP is not trying to cheat and bill more usage time -- to the contrary of what is said in section 2.8, btw). However, this requires that the key remain local (in the AAA server). But one wouldn't want to preclude the use of the key for encryption either (even though the NAS/AP operator can then decrypt the data, it's still better than clear data over the air in the case of 802.11 connections). I still think deriving two keys (by deriving a longer key and splitting it, for instance) would be the better solution. 3. The E bit is not protected. Not sure if that's actually an issue (my tortuous mind hasn't come up with a case yet), but maybe somebody else can find one ;-> 4. I think a quick mention of the username hiding (pseudonym) feature in section 1 would be a good thing. Always better to describe what you're talking about before that stuff popping up in the description of the packets :-) Thanks, Jacques. _________________________________________________________ Do You Yahoo!?

Many thanks! I'm just about to leave for a vacation, and I only have time for a quick comment. A security consideration about Step Two of section 3.2. occurred to me: Here the plaintext is the user identity, which an attacker might know. Can this known plaintext-ciphertext pair enable the attacker to compromize the key K? I don't know, I'm not familiar with this usage of SHA1. As Jacques mentioned, it makes sense to use different keys for each purpose. We could use K for key derivations only, and derive a pseudonym hidding key, a link-layer packet security key and a lightweight re-authentication key from it. The AAA server would only transport the packet security key the NAS, others would remain "end-to-end". Therefore it would be impossible for the NAS to extract hidden pseudonyms or to fake lightweight re-authentications on behalf of the client. This would also restrict the implications of key compromises: for example even if the pseudonym hidding key was compromised, link layer packet security or re-authentication would not be compromised. I think we could copy key derivation ideas from IKE (RFC 2409) or TLS (RFC 2246).

A list of Internet-Drafts directories can be found in http://www.ietf.org/shadow.html or ftp://ftp.ietf.org/ietf/1shadow-sites.txt Internet-Drafts can also be obtained by e-mail. Send a message to: mailserv@ietf.org. In the body type: "FILE /internet-drafts/draft-ietf-pppext-posvcholo-04.txt". NOTE: The mail server at ietf.org can return the document in MIME-encoded form by using the "mpack" utility. To use this feature, insert the command "ENCODING mime" before the "FILE" command. To decode the response(s), you will need "munpack" or a MIME-compliant mail reader. Different MIME-compliant mail readers exhibit different behavior, especially when dealing with "multipart" MIME messages (i.e. documents which have been split up into multiple messages), so check your local documentation on how to manipulate these messages. Below is the data which will enable a MIME compliant mail reader implementation to automatically retrieve the ASCII version of the Internet-Draft. --NextPart Content-Type: Multipart/Alternative; Boundary="OtherAccess" --OtherAccess Content-Type: Message/External-body; access-type="mail-server"; server="mailserv@ietf.org" Content-Type: text/plain Content-ID: <20010723141021.I-D@ietf.org> ENCODING mime FILE /internet-drafts/draft-ietf-pppext-posvcholo-04.txt --OtherAccess Content-Type: Message/External-body; name="draft-ietf-pppext-posvcholo-04.txt"; site="ftp.ietf.org"; access-type="anon-ftp"; directory="internet-drafts" Content-Type: text/plain Content-ID: <20010723141021.I-D@ietf.org> --OtherAccess-- --NextPart-- From owner-ietf-ppp@merit.edu Thu Jul 26 10:45:50 2001 Received: from trapdoor.merit.edu (postfix@trapdoor.merit.edu [198.108.1.26]) by ietf.org (8.9.1a/8.9.1a) with SMTP id KAA13916 for ; Thu, 26 Jul 2001 10:45:49 -0400 (EDT) Received: by trapdoor.merit.edu (Postfix) id 59B9791225; Thu, 26 Jul 2001 03:03:31 -0400 (EDT) Delivered-To: ietf-ppp-outgoing@trapdoor.merit.edu Received: by trapdoor.merit.edu (Postfix, from userid 56) id A6B5991228; Thu, 26 Jul 2001 03:03:30 -0400 (EDT) Delivered-To: ietf-ppp@trapdoor.merit.edu Received: from segue.merit.edu (segue.merit.edu [198.108.1.41]) by trapdoor.merit.edu (Postfix) with ESMTP id B4EAF91225 for ; Thu, 26 Jul 2001 03:02:31 -0400 (EDT) Received: by segue.merit.edu (Postfix) id 623E55DDA8; Thu, 26 Jul 2001 03:04:30 -0400 (EDT) Delivered-To: ietf-ppp@merit.edu Received: from smtp010.mail.yahoo.com (smtp010.mail.yahoo.com [216.136.173.30]) by segue.merit.edu (Postfix) with SMTP id D39415DD9D for ; Thu, 26 Jul 2001 03:04:29 -0400 (EDT) Received: from ppp-203-197-9-195.bom.vsnl.net.in (HELO muralidharan) (203.197.9.195) by smtp.mail.vip.sc5.yahoo.com with SMTP; 26 Jul 2001 07:03:04 -0000 X-Apparently-From: Message-ID: <000701c115a1$6e4ad340$1000a8c0@muralidharan> Reply-To: "R.

In view of this, it is suggested that the following be considered: Section 3 be modified to include the following info for lower order VC. For higher order VC, SONET POH bytes C2 and H4 are used and for Low order VC, the POH byte C2 and VT overhead byte V5 are used. Further, when an STS-1 carries VT traffic containing POS which is virtually concatenated, is there special symbol for the C2 byte defined? This condition occurs when one tries to map 10Mbps Ethernet traffic onto 7 VT1.5s in low order VC mode.
