Security Based Protocol Design for In-Vehicle Controller Area Network

Vehicle networks which are currently connected to external networks permit conflicts to perform a long-range wireless attack using CAN susceptibilities. In this article shows that a long range of wireless attack is feasible using a real vehicle and a destructive Smartphone application in a connected car scenario. A security protocol is suggested for CAN as to plan in agreement with ongoing CAN requirements and also exhibits an active wireless attack using a real vehicle on a connected car scenario, in which a motorist's Smartphone is attached to the in-vehicle CAN. The attack examination involves two phases; they are preliminary and actual attack. In the preliminary phase, before initiating an actual attack, an attacker first attain a CAN data frame to impact control of the target vehicle using a diagnostic tool. The outcome shows that the suggested security protocol is more efficient than existing security protocols with reference to authentication delay and communication load.
