This season’s final Maritime Cyber Security Centre Research Seminar will be conducted via MS Teams on 18 June at 13:00-15:00 (see the link below). Ömer Melih Gül, PhD, Associate Professor at Istanbul Technical University, will be presenting on the topic of “AI/ML based RF Fingerprinting for spoofing attacks and AI/ML based Maritime Security for AIS data spoofing attacks.”
Introductory remarks by the speaker

Industrial IoT-enabled critical infrastructures are susceptible to cyber-attacks due to their mission-critical deployment. To ensure security by design, radio frequency (RF)-based security is considered an effective way for wirelessly monitored or actuated critical infrastructures to analyze unique transmitter fingerprints and determine the legitimacy of a user device or transmitter. An RF fingerprinting model is susceptible to various channel and environmental conditions that impact the learning performance of a machine/deep learning model. As data gathering cannot always be considered a feasible alternative, efficient solutions that can tackle the impact of varying propagation channels on learning performance are emergent. We aim to shed light on the RF fingerprinting problem from a different angle when 4G, 5G, and WiFi data samples are collected from different transmitters by proposing a fine-grained augmentation approach to improve the learning performance of a deep learning model with an enhanced classifier structure. We also present a sensitivity analysis of the fine-grained approach concerning different signal-to-noise-ratio (SNR), signal-to-interference-ratio (SIR) levels, and signal-to-interference-plus-noise-ratio (SINR) levels to exhibit the resiliency of the fine-grained augmentation approach against interference and noise. We will also talk about a new threat emerging in global maritime domain, AIS spoofing. This deceptive shipping practice involves tampering with the Automatic Identification System (AIS), which is used to broadcast vessel position, providers identity, and other critical information to nearby vessels and maritime authorities, initially used for collision avoidance. As AIS spoofing incidents rise, it has severe implications for shipping, national security, safety of life, and global trade. We will present several recent approaches including AI/ML based solutions for the problems of AIS data spoofing attacks.
