Protected AIS: A Demonstration of Capability Scheme to Provide Authentication and Message Integrity [PDF]

open access: yesTransNav, 2020
The Automatic Identification System (AIS) provides situational awareness for vessels at sea. AIS has a number of known security vulnerabilities that can lead to a several types of attacks on AIS, including the ability to create ghost vessels, false ...

Monitoring in Near-Real Time for Amateur UAVs Using the AIS

open access: yesIEEE Access, 2020
The use of drones or UAVs (unmanned aerial vehicles) for commercial or leisure purposes is increasingly common in our society. However, UAVs can also be used for other purposes that may compromise the privacy and safety of the population. For this reason,
