ABSTRACT:
With the dense deployment of femtocells in
enterprise femtocell network and the small coverage of femtocells, handover in
enterprise femtocell network will be frequent. The general handover key
derivation method which is used in handover procedures in LTE is not suitable
for handover in this scenario because of its long time cost and the weak
security. To solve this problem, this paper has proposed a new local gateway
assisted handover key derivation schema in enterprise femtocell network. It can
meet the fast derivation and good forward/backward key secrecy requirement of
handover key derivation in enterprise femtocell network. The simulation result
has verified that the proposed handover key derivation schema works better than
the existing method.
