Abstract:
Navigating at sea has undergone a significant transformation, shifting from traditional navigation methods based on landmarks and celestial objects to the utilization of advanced technology such as the Global Positioning System (GPS). However, the emergence of GPS spoofing as a pervasive cyber threat poses substantial risks to maritime navigation, introducing vulnerabilities and potential disruptions to critical systems. This research aims to address the shortcomings of current defensive strategies, which are often hindered by their high costs, limited effectiveness, or impracticality in real-world maritime scenarios. Moreover, maritime GPS spoofing has been overlooked despite extensive research on general anti-spoofing techniques. To fill this research gap, a novel framework is proposed that leverages the concept of Order Preserving Encryption, a scheme that allows efficient range queries on encrypted data while maintaining the order. The framework is designed with confidentiality, integrity, and availability as primary objectives, achieved through the implementation of encryption, cloud storage, and comprehensive data comparison techniques. To evaluate the efficacy of the proposed scheme, an extensive analysis is conducted on a real-world dataset obtained from the searoutes.com API.
