	Title		: Selection of MIPv6 Security Level Using a Hashed

MIPv6 is being defined with a security solution called Return
Routability (RR) that does not need any authentication infrastructure.
Given that the solution is 'infrastructureless' in this manner, it
isn't very easy to control the solution once it is widely deployed. In
particular, it isn't clear how the solution could be changed to a new
solution, should that ever become necessary. Peers should be able to
agree about the use the new solution in a secure manner, without Man-
in-the-Middle attackers from being able to mount a Bidding Down attack
and downgrade the security back to the original solution. This draft
specifies a simple but secure scheme which allows nodes to choose what
security solution they use. One currently known drawback of this
scheme is that it is based on a technology that has IPR considera¡
tions.

NOTE:	The mail server at ietf.org can return the document in
	MIME-encoded form by using the "mpack" utility.  To use this
	feature, insert the command "ENCODING mime" before the "FILE"
	command.  To decode the response(s), you will need "munpack" or
	a MIME-compliant mail reader.  Different MIME-compliant mail readers
	exhibit different behavior, especially when dealing with
	"multipart" MIME messages (i.e. documents which have been split
	up into multiple messages), so check your local documentation on
	how to manipulate these messages.
