Re: Identifiers

 In your previous mail you wrote:

   Our problem is not ownership. It is surviving changes in existing
  connectivity without opening the door to hijacking or DoS. All we need
  to authenticate is that after a multihoming event, we are still
  talking to the same entity at the other end.
   
=> this is a different problem: the binding between the identifier and
the locators and we can divide it into three parts:
 - can be the multi-homing signaling modified by an attacker on the path?
 - have we to trust the peer not to give a fake locator?
 - have we better properties about locators?
As in multi-homing we have static locators even the last part can be
a reasonable goal.
But the subject of this thread is "Identifiers" so I don't understand
your intent...
