Priscilla,
Questions arose while trying to explain proposed TCP fixes to my students. Can y'all help me with these?
We were going over the "Transmission Control Protocol security considerations draft-ietf-tcpm-tcpsecure-00.txt" document here when the questions arose:
http://www.ietf.org/internet-drafts/draft-ietf-tcpm-tcpsecure-00.txt
Meta-response: look at the discussion over at the IETF, in the tcpm Working Group. There's a nice summary as well as some interesting discussion on possible issues with these fixes. Unfortunately, the tcpm mailing list archive seems to be accessible via FTP as large monthly mailbox files only, so I cannot point you to the relevant individual messages. The threads are called "new work item: TCP security issue" and "draft-ietf-tcpm-tcpsecure". (There's also a lot of process discussion in there, about the way this issue was initially handled by a closed group and then presented as a work item for the working group. This is interesting but only marginally helpful to understand the technical content of the changes.) Oh no, wait, there's another mail archive for tcpm (not listed on the "official" WG page (http://www.ietf.org/html.charters/tcpm-charter.html): The threads start in https://www1.ietf.org/mail-archive/working-groups/tcpm/current/msg00086.html https://www1.ietf.org/mail-archive/working-groups/tcpm/current/msg00095.html A nice summary of the changes by David Borman: https://www1.ietf.org/mail-archive/working-groups/tcpm/current/msg00130.html Hope this helps, -- Simon.
