Abstract  Abstract

a new key management approach is provided to protect communication handoffs between an access terminal and two access points. as an access terminal moves from a current access point to a new access point, the access terminal sends a short handoff request to a new access point. the short handoff request can include the access terminal id; it does not include the access point id. the new access point can then send its identifier and the access terminal identifier to the authenticator. using a temporary master key previously generated, the access point identifier and the access terminal identifier, an authenticator can generate a session master key. the session master key can then be sent to the access point by the authenticator. the access terminal independently generates the same new security key with which it can safely communicate with the new access point.
