Analysis of fuzzy evidence accrual security approach To GPS systems

摘要

GPS security is becoming a major concern. In this paper, an evidence accrual system that looks to identify when a GPS navigation system may be compromised is discussed. The techniques use a novel fuzzy Kalman filter to drive the evidence generation. The technique has been modified for a more realistic set of operations that considers possibilities, including variations on jamming or spoofing and the detection capabilities that can be used.
