Abstract: A method for monitoring operation of a controller area network (CAN) comprising a plurality of nodes. The method comprises measuring a voltage associated with a CAN message transmitted on the network, determining a message signature in dependence on the measured voltage, and comparing the message signature with a node signature to determine the authenticity of the CAN message. One or more actions may be taken in dependence on the determined authenticity.
