When two messages with the same ID but different contents appear on the bus simultaneously, it results in a message collision. This can result in loss or delay of critical information. If done deliberately by malicious actors, it can lead to unsafe conditions. In this paper, the goal is to motivate the need for a solution against message collisions and propose a concept of a one time programmable CAN message collision avoidance filter that needs no updates or secure storage.enController Area Network(CAN)FilterIn-Vehicle NetworksMessage CollisionsComputer Science, Information and General Works::005: Computer Programming, Programs, Data and SecurityTechnology::620: EngineeringSocial Sciences::388: TransportationConference Paperhttps://www.thinkmind.org/library/CYBERConference Paper
