Abstract
A method, non-transitory computer readable medium, device, and system that detects a replay attack includes monitoring Global Navigation Satellite System (GNSS) time obtained by a GNSS receiver from a GNSS signal from a GNSS satellite. An alert condition for the replay attack is identified based on at least a detected delay between a universal coordinated time (UTC) and the GNSS time. An alert notification is provided based on the identification of the alert condition for the replay attack.
