Hi Tom,

To= clarify, my concern is about:
(1) CBA is still an individua= l draft
(2) CBA is applied as a "MUST"

IMHO= , only copying text inside the document is a bad idea: using such a securit= y mechanism for a proposed Standard track document needs deep security revi= ews (e.g., Security Area at least).

Best regards,

JMC.

o Mobile IP(v6) v.s. HIP
At first, I prefer to be frank: I must admit that I am not pro-HIP ...
HIP,=C2=A0 IMHO, looks like Mobile IP(v6) (modulo some parameters) with man= y
drawbacks ...

Now, please, trust me, my review has been done with a _neutral_ point of view.

o HIP Security
I didn't review HIP basis RFCs/drafts, meaning that my review is based<= br> on the fact that security reviews have already been done.

o draft-ietf-hip-rfc5206-bis-12

My main concern is the use of an Informative RFC to provide security to
the protocol described inside this document:
Section 5,6, "To prevent redirection-based flooding attacks, the use o= f
a Credit-Based Authorization (CBA) approach MUST be used when a host
sends data to an UNVERIFIED locator."

 Thank you for the review; is your concern that the CBA mechanism is used al= together, or that the specification relies on an Informative RFC (in which = case it may be remedied by avoiding the normative reference by copying into= this draft)?

- Tom
