Abstract

The invention provides a message anomaly detection method and device, electronic equipment and a storage medium, and the method comprises the steps: carrying out the statistics of preset type messages through employing a message counter in a basic software BSW layer of an Autosar system, and obtaining a first message number; obtaining a to-be-matched index corresponding to the preset type of message, and calculating a second message quantity according to the to-be-matched index; and determining a message exception result of the preset type of messages according to the first message number and the second message number. A message counter is arranged in a BSW layer, the first message number of preset type messages actually counted by the message counter is directly obtained, and a message exception result is determined according to the actually counted first message number and the theoretically calculated second message number. The time-consuming operation of performing feature matching with the pre-stored security threat message in the ASW layer is effectively avoided, so that the efficiency of performing anomaly detection in an Autosar system classical platform is improved.

Description

technical field [0001] The present application relates to the technical fields of Internet of Vehicles, network security threat detection, and message abnormality detection, and in particular, to a message abnormality detection method, device, electronic device, and storage medium. Background technique [0002] AUTomotive Open System ARchitecture (Autosar) is a standardized software framework for intelligent mobility. The Autosar system includes two types: Classic Platform and Adaptive Platform; Security and determinism, adaptive platforms focus primarily on adaptive deployment of applications and interaction with classic platforms or other non-Autosar systems. [0003] At present, in order to prevent attackers from invading the Controller Area Network (CAN) bus of the Internet of Vehicles to gain control of the entire vehicle, it is necessary to perform anomaly detection on the messages in the classic platform of the Autosar system. The received CAN message is matched with...
