key change for TCP-MD5

  • From: Steven M. Bellovin
  • Date: Mon Jun 19 08:32:49 2006

I just submitted an I-D on TCP-MD5 key change.  Until it shows up in the
official repository, see
http://www.cs.columbia.edu/~smb/papers/draft-bellovin-keyroll2385-00.txt
Here's the abstract:

                The TCP-MD5 option is most commonly used to secure
                BGP sessions between routers.  However, changing
                the long-term key is difficult, since the change
                needs to be synchronized between different
                organizations.
                We describe single-ended strategies that will permit
                (mostly) unsynchronized key changes.


Comments welcome.
