Summary:A novel key management approach is provided for securing communication handoffs between and access terminal and two access points. This approach provides for securely handing off communications between an access terminal and access point without risking exposure a master key for the access terminal. Temporary master keys are derived for low latency handoffs and secure authentication between a new access point and the access terminal. In one aspect, a distributive key management scheme is provided in which a current access point generates a new security key (based on its own security key) that is used by the next access point with which an access terminal communicates. In another aspect, a centralized key management scheme is provided in which a central authenticator maintains, generates, and distributes new security keys (based on a master security key associated with the access terminal) to access points.
