http://www.ietf.org/internet-drafts/draft-nikander-mobileip-v6-ro-sec-01.txt is a background document, produced by the MIPv6 route optimization security design team, that tries to explain the security desing in MIPv6 RO. I think that most of the threats and much of the solution model would most probably apply also to SCTP ADD-IP and, of course, also other multi-address multi-homing solutions.
