Methods and apparatuses for handover key management are provided according to one or more embodiments. A wireless transmit/receive unit (WTRU) may be handed over from a source base station to a target base station. The source base station may request a handover to a WTRU context management function (UCF). The UCF may generate a freshness parameter associated with the target base station. The UCF may utilize the freshness parameter to generate one or more access stratum (AS) keys. The freshness parameter may be provided to the WTRU by the UCF via the source base station. The WTRU may also utilize the freshness parameter to generate the one or more AS keys. The one or more AS keys may be securely shared with the target base station. The one or more AS keys may be utilized for securing an AS communication between the WTRU and the target base station.
