Abstract  Abstract

(57) Abstract: A novel key management approach Receive a request from an access terminal to establish a secure communication session, the request not including an access point identifier. is provided for securing communication handoffs between an access terminal and two access points. As an access terminal moves from a current access l104q Send a first access point identifier and optionally an associated value to the authenticator. (Optional) Send the associated value to the access terminal. point to a new access point, the access terminal sends a short handoff request to the new access point. The short handoff request may include the access terminal ID; it does not include the access point ID. 1 The new access point may then send its identifier attd the access terminal's identifier to the authenticator. ii06 Receive a first master session key from the authenticator J ii08" __ Establish the secure communication session with the access terminal using the first master session kev. Using a previously generated master transient key, the access point identifier and the access terminal identifier, an authenticator may generate a master session key. The master session key may then be sent to the access point by the authenticator. The access terminal independently generates the same new security key with which it can securely communicate Receive a request from the access terminal to handoff the secure with the new access point. communication session to a second access point. Send a second access point identifier, access terminal identifier and optionally a second associated value to the authenticator. 1113<(Optional) Send tile second associated value to the access terrnirlal.
