Light-Weight Platform for Attack Validation in LTE Network

Within the scope of Long Term Evolution (LTE) security research, open-source implementations of LTE stack are generally used to validate attacks. Since analysis of the code requires advanced understanding of both specifications and programming, validating attacks is tiring and time-consuming. To address the difficulty, we develop LTE Evaluation Assistant Platform (LEAP), an extension of OpenAirInterface (OAI). It provides a Python interface to monitor and manipulate traffic inside OAI. LEAP adopts a novel architecture to reduce complexity. We also investigated the tradeoff between high level customization, usability, and latency. The evaluation result shows LEAP could effectively simplify attack validation process.
