By implementing OSNMA, navigation programs can present extra dependable and trusted positioning data to vessels, which improves security and effectivity within the maritime business.
E-warfare at Sea
In the late Nineties, the maritime business stakeholders constructed the principle Navigator, ECDIS, and AIS programs to enhance maritime security and safety. While the event and deployment of AIS within the final decade have considerably contributed to elevated navigational security, it has additionally led to a number of security and safety issues. One of the key points is spoofing, the place the vessel’s AIS information is manipulated.
According to a report by the Center for Advanced Defense Studies (C4ADS), Russia has been manipulating GNSS alerts since at the very least 2016. The report, primarily based on satellite tv for pc information collected by the International Space Station (ISS), recognized 9,883 suspected spoofing incidents in 10 world areas linked to the Russian army (Gary C. Kessler, CISSP DEFCON, 04/2019). The focused areas embrace the Black Sea, Crimea, the Russian Federation, and Syria. The examine found that 1,311 civilian ships had been supplied incorrect place coordinates from quite a lot of civilian satellite tv for pc networks, together with an incident within the Black Sea in 2017.
A brand new and cheap digital system has emerged in Asia that’s able to spoofing AIS alerts in ways in which consultants haven’t seen earlier than. This has resulted in a number of spoofing incidents being reported in over 20 coastal areas and ports, together with Shanghai, Fuzhou (Huilutou), Qingdao, Quanzhou (Shiyucun), Dalian, and Tianjin, which have been ongoing for months. Unlike conventional spoofing, the GNSS alerts had been gathered into giant circles, which had been later dubbed “crop circles.” The transferring alerts had been then shifted to the identical place, making a complicated visitors scenario for ship pilots. Due to the low value of GNSS spoofing expertise, these assaults are prone to unfold to different international locations, terrorist teams, criminals, and even particular person operators, posing a critical menace to maritime security.
Existing Countermeasures
What measures might be taken to detect GPS/GNSS spoofing? One methodology is to detect sign distortion on the level when the pretend sign overrides the respectable one. Another strategy is to find out that the pretend sign is originating from a special path than the respectable sign. Additionally, encrypted alerts might be correlated to confirm their authenticity, even when the civilian unit can’t interpret the encrypted sign. Employing a GNSS receiver that screens a number of constellations and frequencies with safety capabilities can be an possibility. Also, it’s doable to authenticate the Open Service Navigation Message by means of OSNMA performance.
Ultimately, enhanced cybersecurity is essential. GNSS spoofing has been a safety concern for a few years, and it’s now starting to considerably impression transport. As extra gadgets and autonomous programs depend upon GNSS, a better variety of programs might be inclined to spoofing assaults. With hackers frequently trying to find new methods to use AIS vulnerabilities and spoofing, there will probably be quite a few new cybersecurity vulnerabilities sooner or later, and programs that aren’t adequately secured will probably be susceptible to assault.

On the opposite hand, AIS, because it at present exists, has a number of vulnerabilities which have emerged, largely on account of being primarily based on an open-source system that operates on particular VHF frequencies. The 4 foremost weaknesses are the absence of message integrity, timing, authentication, and validity. If compromised, AIS communications might be intercepted to create fictitious vessels or generate false collision or SOS alerts, occasions that might have critical implications at sea. The vulnerabilities in GNSS programs additionally open the potential of assaults that might impression navigation and AIS-dependent applied sciences. Below are some examples of GPS spoofing assaults which were documented by authorities:
Hacking Scenarios
The vulnerabilities of programs as AIS might be exploited in numerous methods, relying on the kind of hack state of affairs. For occasion, within the closest level of strategy (CPA) spoofing, the attacker creates a misunderstanding of a doable collision with one other ship, inflicting a CPA alert that might lead the sufferer vessel off-course and into hazard. Another hack state of affairs is AIS Search and Rescue Transmitter (AIS-SART) spoofing, the place the attacker sends a pretend misery beacon to lure the sufferer vessel into an attacker-controlled space. A 3rd sort of spoofing assault is climate forecast spoofing, the place the attacker sends false dynamic climate data by way of AIS, making the sufferer ship alter its course.
Denial-of-Service (DoS) assaults are one other type of AIS spoofing that goals to overflow vessels’ AIS updates, flooding adjoining shore services and vessels with extreme information. There can be the frequency hopper assault, the place the attacker sends instructions to shift the sufferer vessel’s AIS to transmit on a particular frequency, making them “invisible” to all however the attacker.
Ghost vessels and information diddling are two different assault eventualities. In the previous, the attacker creates pretend vessels, whereas within the latter, the attacker modifies ship data similar to title, location, course, cargo, sort of ship, and pace. These assaults might be executed by way of software program onshore or inland, or by means of radio frequency (RF) offshore or at sea.
One main safety concern is the supply of AIS information on-line by means of numerous publicly accessible platforms. The IMO committee strongly recommends that nations take authorized measures to guard information from being revealed, as such publicity might severely compromise security at sea.
Acquiring the tools required to spoof GNSS alerts is each low cost and uncomplicated. In the occasion of GPS, civilian alerts aren’t encrypted (L1C, L2C, L5). All that’s wanted is a Software-defined radio (SDR) able to transmitting on L1 frequency (1575.42 MHz). With the help of open-source instruments, it’s simple to jot down a program that may generate GPS NMEA sentences and transmit them by means of SDR for GPS spoofing functions.
