Abstract: Provided is a fraud detection rule updating method enabling the updating of rules that serve as the basis for detecting malicious frames as necessary in an on-board network system. In an on-board network system equipped with multiple electronic control units (ECUs) that communicate via buses and fraud detecting ECUs that determine, based on fraud detection rules, whether messages transmitted on the buses conform to the rules, a fraud detection rule updating method is used in which delivery data including updated fraud detection rules is received from a server external to the on-board network system, and if a certain update condition is satisfied, the fraud detection rules in a fraud detecting ECU are updated to the updated fraud detection rules.

Abstract: An update management method causes an external tool, capable of transmitting an update message to update data such as shared keys within electronic control units (ECUs) making up an onboard network, to update shared keys and the like within the ECUs, while reducing the risk of all ECUs being unauthorizedly rewritten in a case where secret information given to the external tool is leaked. The update management method receives and verifies update authority information indicating authority of the external tool. In a case that an update message instructing updating of shared keys or the like of one or multiple ECUs has been transmitted from the external tool, if the verification is successful and the update authority information indicates that the transmission of the update message is within the range of authority of the external tool, the update is executed at the ECU, and otherwise, update at the ECU is inhibited.
