Abstract
A method for a secure Passive Entry Passive Start (PEPS) authentication protocol measures the walking gait of a user approaching a related vehicle using a passive key device carried by the user. The method also includes measuring the user's gait from the perspective of the vehicle using a vehicle perception system to compare the two and validate the security of an unlock request, authenticate the unlocking session, and protect against relay attacks. The two-factor authentication protocol validates the physical presence and temporal state of the key fob or mobile phone relative to the vehicle using detected key gait measurement (key G-gait) and a vehicle perception-based gait (C-gait) measurement by comparing the independent gaits and generating control commands responsive to consistent and inconsistent measurements.
