Embodiment Construction

[0044] In general, the subject matter described herein relates to improved systems and methods for preventing relay attacks associated with key fobs and similar devices used in conjunction with vehicles and other mobile platforms. In various embodiments, actions are taken based on both motion information (associated with movement of the key device) and location information (associated with the relative position of the key device with respect to the mobile platform). This action may include, for example, preventing access to the mobile platform, preventing activation of the mobile platform, generating an alarm signal, and disabling receipt of requests to enter the mobile platform or requests to activate the mobile platform.

[0045] As a preliminary matter, there is no intention to be bound by any expressed or implied theory presented in the preceding technical field, background, brief summary or the following detailed description. The term module or control as used herein refe...

Abstract

The present invention relates to a method and apparatus for keys with relay attack prevention, and more particularly, a relay attack prevention system comprising a mobile platform comprising a mobile platform receiver part and a plurality of mobile platform transmitter parts provided therein . The system also includes a key device having a key receiver component, a key transmitter component, and a motion sensor component configured to generate motion information. The key device is configured to receive one or more first signals from the plurality of mobile platform transmitter components at the key receiver component and based on motion information derived from the one or more first signals and The location information optionally transmits a second signal to the mobile platform receiver component.

Description

[0001] Cross References to Related Applications [0002] This application claims priority to US Provisional Patent Application No. 62 / 344,049, filed June 1, 2016, the contents of which are incorporated herein by reference. technical field [0003] The technical field of the invention relates generally to safety systems used in connection with mobile platforms, such as motor vehicles. More particularly, the technical field of the invention relates to systems and methods for preventing relay attacks and other such security risks in the context of wireless communication systems. Background technique [0004] Mobile platforms, such as motor vehicles, marine vessels, etc. often employ electronic key devices to enable entry (eg, passive entry) and / or activation (eg, passive activation) of the mobile platform. Such systems typically employ various low frequency and high frequency RF receiver / transmitters to establish communication between the mobile platform and the key device to ...
