Systems and methods of managing data relay attacks

A system comprising:

• a vehicle controller configured to:
• predict, via a probabilistic analysis, that data associated with one or more messages broadcasted by one or more road-side units is compromised, wherein the prediction is enabled by an algorithm associated with a vehicle controller;
• and
• initiate one or more remedial actions in response to predicting that the data associated with the one or more messages broadcasted by the one or more road-side units is compromised.

A system for validating one or more messages broadcasted by one or more vehicles or one or more road-side units, comprising:

• an infrastructure controller configured to:
• determine, based on a channel busy ratio, whether the one or more messages broadcasted match one or more sanitized operating scenarios;
• select a remedial action from among a plurality of remedial actions in response to determining that the one or more messages do not match the one or more sanitized operating scenarios;
• and
• cause the one or more vehicles to initiate the remedial action.
