Abstract
A system and method are provided for detecting and estimating time synchronization attacks (TSAs) on Global Positioning System (GPS) receivers. The system and method can be implemented to address gaps in the known or proposed TSA detection solutions. In particular, the system and method can be implemented to provide a TSA countermeasure solution that: 1) provides a comprehensive countermeasure against different types of TSAs; 2) allows the GPS receiver to continue its normal operation, which is especially beneficial in Phasor Measurement Unit (PMU) applications where the network's normal operation cannot be interrupted; in other words, the solution not only detects TSAs, but also mitigates their effects so that the network can continue its normal operation; and 3) is relatively simple and capable of being integrated with current GPS receivers without having to alter the circuitry of the GSP receivers.
