内容摘要：The introduction of mobile relay node (MRN) in LTE-advanced high-speed rail networks is an attractive approach to provide uninterrupted connectivity for a group of user equipment on board. However, MRNs still suffer from frequent handovers and several security threats due to several rounds of message exchange and the insecure air interface between MRNs and donor eNBs (DeNBs). In this talk, I will present a group-to-route handover authentication scheme based on trajectory prediction for mobile relays.
By this scheme, all of the DeNBs deployed along the trajectory can be formed a route-DeNB group and all of the MRNs deployed in the same train can construct a MRN group. Compared with the current existing solutions, the proposed solution can accomplish a mutual authentication and key agreement between the MRN group and the target DeNB with an ideal efficiency in terms of authentication signaling overhead, bandwidth consumption, and computational cost. Security evaluation by using BAN logic and formal verification tool, Scyther, shows that the proposal can work correctly with the ability to withstand several protocol attacks.
