APPARATUSES AND METHODS FOR SECURITY IN BROADCAST SERIAL BUSES

摘要

Apparatuses and methods are disclosed for monitoring broadcast serial communication buses, analyzing communications on those buses, and providing information relative to the monitoring and analysis. A CAN bus is used as an example to provide details of analysis of a broadcast serial bus. Metadata and temporal neighbor history for each type of message identifiers are developed and analyzed. Alerts may be generated if the metadata, the temporal neighbor history, or a combination thereof fall outside predetermined tolerance levels.
