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.The LTE transport network contains three segments, namely, radio access, backhaul, and core networks. The backhaul network further subdivides into two sections: access and aggregation networks. Figure 1 illustrates a simple LTE transport network.The access network connects eNBs sites to aggregation nodes. Usually, it has a tree and/or chain topology. The aggregation network very often has a ring and/or mesh topology. It is normally terminated at the core network where S-GWs and MME devices are located. Hence, the backhaul network extends from the first transport equipment connecting cell sites (e.g., eNBs sites) to the transport aggregation equipment connecting central sites (e.g., S-GWs/MME sites) [12]. In addition, the LTE backhaul network contains several traffic transport interfaces (e.g., S1 and X2). Security issues of long-term evolution backhaul network3GPP specifications propose an entirely new flatten and all-IP-based architecture for the LTE backhaul network. It distributes some of the control functionality throughout the network. Hence, it pushes more intelligence to end nodes such as eNBs. These properties redefine the security and other service requirements of the LTE backhaul network.Long-term evolution networks face new security threats that did not exist before or were harder to exploit in previous 2G/3G mobile backhaul networks. The security threats originate at various sections of LTE network, namely, customer nodes, backhaul network, customer provider interface network, radio access network, and core network. Hence, it is necessary to implement dedicated security mechanisms in each section to avoid these potential threats. This research focuses on the possible threats only on the Security Comm.

The rapid progress made in mobile device technologies has implied that the access network must evolute and develop new strategies to satisfy the requirements of the users. Heterogeneous network (HetNet) allows for a flexible deployment strategy and offers economically viable solutions to improve network scalability and indoor coverage. This emerging topic has caught the attention of the research community and the industry because of the importance of these networks to satisfy the demand of data services. To provide this demand, different parameters of quality of service (QoS) must be satisfied. In this paper, we present a study on recent advances and open research issues on Mobility Protocols in conjunction with Multi-Protocol Label Switching (MPLS)-based packet transport networks (PTN) to provide QoS in wireless heterogeneous networks. Various mobile management protocols and their interaction with the mobile backhaul and packet core network are briefly introduced. A new architecture called Integrated Proxy Mobile MPLS-TP (IPM-TP) is also outlined to reduce the signalling cost and improve the QoS in HetNets with high rates of mobility.

Software Defined Networking (SDN) and its one possible realization, OpenFlow, define the trends of future networks. However, the present OpenFlow architecture does not allow the switches to be mobile e.g., in a moving train as it would disrupt flow processing from network switches. We present OFHIP, an architecture that enables OpenFlow switches to change their IP addresses securely during mobility. OFHIP employs IPSec encapsulated security payload (ESP) in transport mode for protection against DoS, data origin authenticity, connectionless integrity, anti-replay protection, and limited traffic flow confidentiality. We demonstrate the benefits of OFHIP compared to present use of SSL in enabling mobility, reducing the connection latency and improving the resilience to known TCP-level attacks.
