GNSS Spoofing Detection and Mitigation Based on Maximum Likelihood Estimation [PDF]
Sensors, 2017 Spoofing attacks are threatening the global navigation satellite system (GNSS). The maximum likelihood estimation (MLE)-based positioning technique is a direct positioning method originally developed for multipath rejection and weak signal processing. We find this method also has a potential ability for GNSS anti-spoofing since a spoofing attack that ...

A Multi-Antenna Scheme for Early Detection and Mitigation of Intermediate GNSS Spoofing
Sensors, 2019 This article presents a method for detecting and mitigating intermediate GNSS spoofing. In this type of attack, at its early stage, a spoofer transmits counterfeit signals which have slight time offsets compared to true signals arriving from satellites ...

Foundations of GNSS Spoofing Detection and Mitigation with Distributed GNSS SDR Receiver [PDF]
TransNav, 2018 GNSS spoofing is an intentional and malicious action aimed at degrading and suppressing GNSS Positioning, Navigation, and Timing (PNT) services. Since it affects data and information segment of GNSS, it is considered a GNSS information (cyber-) security ...

Navigation, 2023 To address phasor measurement unit (PMU) vulnerability to spoofing, we propose the use of a set-valued state estimation technique known as stochastic reachability (SR)-based distributed Kalman filter (DKF) that computes secure global positioning system ...

GNSS Spoofing Mitigation Using Multiple Receivers
2020 IEEE/ION Position, Location and Navigation Symposium (PLANS), 2020 GNSS receivers are vulnerable to spoofing attacks, where false satellite signals are transmitted to trick the receiver to provide false position and/or time estimates. Novel algorithms are proposed for spoofing mitigation by exchanging double differences of pseudorange, or carrier phase, measurements between multiple GNSS receivers.

Mitigating Address Spoofing Attacks in Hybrid SDN [PDF]
International Journal of Advanced Computer Science and Applications, 2017 Address spoofing attacks like ARP spoofing and DDoS attacks are mostly launched in a networking environment to degrade the performance. These attacks sometimes break down the network services before the administrator comes to know about the attack condition.

Mitigation of GNSS Time Synchronization Attacks in a Multicorrelator Receiver
IEEE Access, 2022 Global navigation satellite systems (GNSSs) are widely used in various fields to provide high-precision timing. However, their low signal power and open signal structure render GNSS receivers vulnerable to time synchronization attacks (TSAs).

Research on flood defense mechanism of SDN control layer:detection and mitigation
Tongxin xuebao, 2021 Aiming at the problem of spoofing flood defense in the control layer of SDN, a controller defense mechanism (CDM)was proposed, including a flood detection mechanism based on key features multi-classification and a flood mitigation mechanism based on SAVI.
