US Patent 10491405 Cryptographic security verification of incoming messages

Systems and methods for cryptographic security verification include receiving, using a dedicated short range communications system, a message from a remote vehicle or an infrastructure system. A processor determines whether a current number of attempted message verifications per second is less than a predetermined threshold. The processor performs verification of the message in response to determining that the current number of attempted message verifications per second is less than the threshold. The processor determines whether the message falls within at least one predetermined category of message type and performs verification of the message in response to the current number of attempted message verifications per second not being less than the threshold and the message falling within the at least one predetermined category of message type. The processor processes the message in response to the message being verified.
