Abstract: A method of monitoring messages from a sensor using an integrated circuit is provided, wherein the messages include data measured by that sensor. The method includes reading a first message from interconnect circuitry of the integrated circuit, the interconnect circuitry connecting the sensor to one or more core devices configured to process the message. The method further includes calculating a first hash value for the first message and comparing the first hash value to one or more prior hash values stored in a hash store, wherein each prior hash value corresponds to a message that was read from the interconnect circuitry prior to the first message. The method further includes performing a corrective action when the difference between the first hash value and at least one of the prior hash values stored in the hash store is above a predetermined threshold.
