Modern society relies on the continuous and reliable availability of mobile communication services. From emergency responders and healthcare to transportation and industry, 5G and future 6G networks form the backbone of our digital infrastructure. At the same time, these networks are becoming increasingly attractive targets for sophisticated jamming and spoofing attacks, threats capable of disrupting communication precisely when it is most needed. This leads to the following security threats:
- Disruptions to industrial and societal infrastructure.
- Loss of critical communication services.
- Reduced emergency response capability.
Rise in intelligent jammers
Traditional jamming attacks are relatively easy to detect. However, we now see a rise in intelligent jammers that analyse signals in real time, target specific parts of the 5G waveform, and adapt their behaviour to avoid detection. These attacks can be low power, stealthy, and highly effective at degrading network performance.
New methods to mitigate attacks on 5G networks
AEGIS aims to provide new defence mechanisms capable of countering these emerging threats by combining deep knowledge of 5G/6G technology with signal processing, AI/ML, and network analysis. This includes:
- New methods for detecting intelligent jamming and spoofing. We explore classical statistical techniques as well as state of the art AI/ML to identify anomalies in radio signals and network behaviour.
- Classification of attack types. We design algorithms capable of distinguishing between continuous, deceptive, reactive, coordinated, and other forms of advanced interference.
- Localization of jamming sources. The project develops methods to estimate the position of one or more jammers using measurements collected from user equipment and the network.
- Integration into real 5G networks. Selected methods are implemented and validated in SINTEF’s private 5G network in Trondheim, using open source RAN platforms as well as commercial equipment.
Collaboration project
The project involves a PhD student and several MSc students at NTNU, strengthening national expertise in secure mobile communication technologies.
The project collaborates with international research partners, including Aalto University. Industry partners such as Telenor and Bittium ensure relevance for real-world operation and security needs.
