12. The method of claim 9, wherein providing the information indicative of the first key comprises providing the information indicative of the first key in response to determining that the mobile unit is being handed off to the second base station
13. The method of claim 9, wherein providing the information indicating that the first key is temporary comprises providing the information indicating that the first key is temporary to at least one of the mobile unit, the second base station, and the second access serving network
14. The method of claim 9, wherein providing the information indicating that the first key is temporary comprises providing the information indicating that the first key is temporary in response to determining that the mobile unit is being handed off to the second base station
15. The method of claim 9, comprising providing a random number and data encrypted using the random number and the first key to the second base station
16. A method of wireless communication involving a mobile unit, at least one first base station having a secure association with a first access serving network represented by a first pairwise master key, the first access serving network having a secure association with an authentication server and at least one second base station associated with a second access serving network that does not have a secure association with the authentication server, the method comprising:
receiving information indicative of a first key generated by the first access serving network using the first pairwise master key;
receiving information indicating that the first key is temporary; and
establishing a temporary security association with the mobile unit using the first key.', 'receiving information indicative of a first key generated by the first access serving network using the first pairwise master key;', 'receiving information indicating that the first key is temporary; and', 'establishing a temporary security association with the mobile unit using the first key
17. The method of claim 16, wherein receiving said information indicative of the first key comprises receiving information indicative of a first key generated using the first pairwise master key associated with the first access serving network and an identifier associated with the second base station
18. The method of claim 17, wherein receiving the information indicating that the first key is temporary comprises receiving information indicating that a second pairwise master key is to be generated by the second access serving network
19. The method of claim 18, comprising negotiating the second pairwise master key with the mobile unit.
20. The method of claim 19, comprising receiving a request to negotiate the second pairwise master key from the mobile unit when the mobile unit determines that channel conditions are reliable enough to conduct mutual authentication, and wherein negotiating the second pairwise master key comprises negotiating the second pairwise master key in response to receiving the request from the mobile unit.
21. The method of claim 16, comprising receiving a random number and data encrypted using the random number and the first key from the second base station.']
