Abstract:
The development of passive keyless entry and start (PKES) systems in modern vehicles enables drivers to access and control their vehicles remotely using smart keys, which improves the driving conveniences. The PKES system verifies the smart key identity if the communication channel between the vehicle and the smart key is established. When the message in the communication channel is relayed by other devices, it can be manipulated by the attackers and the PKES systems become vulnerable. The distance bounding protocol, which estimates the physical proximity between the vehicle and the smart key, is one of the countermeasures against relay attacks. In this paper, the time-based distance bounding is studied. Since the effectiveness of distance bounding protocol relies heavily on the estimation accuracy, various time-based estimation algorithms are enumerated and compared in this paper.
