RA-Sentinel AoA
Direction aware sensing of RF-based attacks
RA-Sentinel is a small, low-power wide band radio receiver device that automatically detects various malicious attacks on Wifi access points, such as Man in the Middle and Denial of Service attacks. The RA-Sentinel project is designed to protect your home WiFi from unwanted cyber threats. Think of it as a digital watchdog for your internet connection that barks when someone from the outside tries to break in. The device will enhance internet safety for ordinary users by monitoring any Wifi cell. The RA-Sentinel Multi-Channel project aims to enhance the existing RA-Sentinel system by developing a 4-channel, 2.4 GHz RF front-end. This upgrade will enable the system to determine the direction of RF-based attacks. By introducing a multi-channel, phase-coherent reception system, we can estimate the Angle of Arrival (AoA) of incoming signals. This will help identify and locate threats such as jamming, spoofing, or unauthorized transmissions.
This project was funded through the NGI0 Commons Fund, a fund established by NLnet with financial support from the European Commission's Next Generation Internet programme, under the aegis of DG Communications Networks, Content and Technology under grant agreement No 101135429. Additional funding is made available by the Swiss State Secretariat for Education, Research and Innovation (SERI).
