Behavioral Model Anomaly Detection in Automatic Identification Systems (AIS)

2020 10th Annual Computing and Communication Workshop and Conference (CCWC), 2020
Over 90% of all goods in the world, at some point in their life, are carried on a vessel at sea. Currently, the maritime industry relies on the Automatic Identification System (AIS) for collision avoidance, vessel tracking, and vessel awareness while operating at sea. AIS is a plaintext, unencrypted, unauthenticated protocol and, as such, is vulnerable
