Abstract:
A security implementation method includes receiving, by a first network element, a request for handing over user equipment from a source access network device to a target access network device to perform communication. The method further includes obtaining, by the first network element, a security key, where the security key is used for protecting the communication between the user equipment and the target access network device after the user equipment is handed over from the source access network device to the target access network device, and sending, by the first network element, the security key to the target access network device.

Claim (Index 1):
A key derivation method in a handover of a user equipment (UE) from a fifth generation communications system to a Long Term Evolution (LTE) system, the method comprising:\n receiving, by the UE, a handover command comprising a security context from a first base station in the fifth generation communications system; deriving, by the UE, an intermediate security key (Kasme) of the LTE system based on an intermediate key (Kamf) of the fifth generation communications system; and obtaining, by the UE, an access stratum key based on a network parameter, the Kasme, and the security context, wherein the access stratum key is for protecting a communication between the UE and a second base station in the LTE system.
