Systems and methods for countering security threats in a passive keyless entry system

A non-transitory computer-readable medium for securing wireless communications for passive keyless entry (PKE) to an asset and including instructions that, when executed by one or more processors, cause the one or more processors to:

• monitor operating conditions associated with the asset, the operating conditions identifying security characteristics of the asset and interactions of wireless devices with the asset, and
• selectively activate at least one countermeasure from an available group of countermeasures according to at least the operating conditions, including instructions to selectively activate additional countermeasures beyond the at least one countermeasure from the available group according to the operating conditions and responsive to detecting a malicious attacker, and to monitor the operating conditions including:
• i) detecting nearby wireless communications having a substantially similar transmission frequency, ii) receiving a response at or beyond a timing constraint, iii) identifying a tracked trajectory for a source of a communication that does not correlate with a location proximate to the asset, and iv) identifying a communication that fails to satisfy an active one of the available group of countermeasures;
• and
• wirelessly communicate with an accessing device according to the at least one countermeasure.

A method, comprising:

• monitoring operating conditions associated with an asset, the operating conditions identifying security characteristics of the asset and interactions of wireless devices with the asset, including selectively activating additional countermeasures beyond an at least one countermeasure from an available group according to the operating conditions and responsive to detecting a malicious attacker, and to monitor the operating conditions including:
• i) detecting nearby wireless communications having a substantially similar transmission frequency, ii) receiving a response at or beyond a timing constraint, iii) identifying a tracked trajectory for a source of a communication that does not correlate with a location proximate to the asset, and iv) identifying a communication that fails to satisfy an active one of the available group of countermeasures;
• and
• selectively activating at least one countermeasure from the available group of countermeasures according to at least the operating conditions;
• and
• wirelessly communicating, by the asset with an accessing device, according to the at least one countermeasure.
