Abstract

Automatic Identification System, commonly known as AIS, is a maritime communication system that is used to keep track of positions and activities of ships. It is widely implemented all around the world, and mandated on vessels over a certain size according to the International Maritime Organization. It is a signal broadcast over radio frequencies that contains ship characteristics, position, speed, and other information. AIS is also being implemented in aids to navigation, supplementing and in some cases replacing traditional aids such as lighthouses and buoys. The protocol standard contains no security, leaving AIS vulnerable to spoofing, hijacking, and denial of service attacks. This paper explores the possible consequences of AIS exploitation, as well as options to mitigate risk. Digital signature authentication of AIS signals is examined with particular attention paid to the feasibility and challenges of wide scale implementation. Ultimately the potential benefits of digital signature authentication are considered to be outweighed by the challenges of implementation.
