In some architectures and network deployments the MN-HA security
associations may be established as a result of a successful network
access authentication. In such deployments, both the MN and the
Diameter server share the keying material required for computation
and validation of the MN-HA Authentication Option, and a Security
Parameter Index (SPI) for indexing an appropriate security
association. Upon receiving a BU with a MN-HA Authentication Option,
the HA retrieves the keying material required for the computation and
validation of the MN-HA Authentication Option from the Diameter
server. The Diameter request message sent by the HA must contain
enough information (such as SPI, MN-NAI, etc) so that the Diameter
server is able to locate the matching MN-HA security association and
return correct keying material back to the HA.

In case of the Authentication Protocol for Mobile IPv6 [RFC4285],
this specification expects that the Diameter server derives the MN-HA
Security Association and returns the associated session key (i.e. the
MN-HA shared session key) to the HA. However, this specification
does not define nor other IETF specification defines how the Diameter
server actually derives required keys. The details of the key
derivation depends on the deployment where this specification is used
and therefore the security properties of the system depend on how
this is done.
