Novel secure VPN architectures for LTE backhaul networks
In this paper, we propose two secure virtual private network architectures for the long‐term evolution backhaul network. They are layer 3 Internet protocol (IP) security virtual private network architectures based on Internet key exchange version 2 mobility and multihoming protocol and host identity protocol. Both architectures satisfy a complete set of 3GPP backhaul security requirements such as authentication, authorization, payload encryption, privacy protection, and IP‐based attack prevention. The security analysis and simulation results verify that the proposed architectures are capable enough to protect long‐term evolution backhaul traffic against various IP‐based attacks.
