A MITIGATION METHOD AGAINST MESSAGE FLOODING ATTACKS FOR SECURE CONTROLLER AREA NETWORK BY PREDICTING ATTACK MESSAGE RETRANSFER TIME

摘要

In a method performed by a computer, based on a transmission schedule of general CAN messages, an attack message identification step of identifying a general CAN message and a CAN message used in a message flooding attack, an attack node may perform a number of message flooding attacks. When an attack message including a CAN message is transmitted, a dominant bit generation step and a dominant bit, which generate a dominant bit to induce CAN error frame generation in the attack node, cause the attack node to fail to transmit the attack message. In this case, a method is disclosed for alleviating a message flooding attack on a CAN network, including predicting an attack message retransmission time (T
