A Platform Based on srsRAN for Security Research in LTE Network

Because of the fully IP-based heterogeneous network architecture, the Long-Term Evolution (LTE) network faces the threats of malicious attacks. Generally, the open-source Software-Definition Radio (SDR) can be used for attack verification in LTE network. In order to improve research efficiency, we develop a platform based on OAI for attack verification in LTE network, which is called LEAP. However, due to the limitations and flaws of LEAP, we further improve it and develop a platform based on srsRAN for security research in LTE network, which is called LSCAP. LSCAP provides the functions of strategies control, front-end interaction and security data collection. In addition, it uses multi-threading technology to better support the verification of concurrent attacks. Therefore, LSCAP is better at scalability and flexibility than LEAP. In this article, we will introduce the system design of LSCAP and our improvement on LEAP.
