Abstract: Disclosed herein are a lightweight intrusion detection method and apparatus for a vehicle network. The lightweight intrusion detection method may include collecting Ethernet packets from a domain gateway of a vehicle that provides a mirroring port, performing a primary intrusion detection check on the Ethernet packets using a rule-based intrusion detection technique, and performing a secondary intrusion detection check on the Ethernet packets using a machine learning-based intrusion detection technique when no intrusion attack is detected as a result of the primary intrusion detection check.

Abstract: Disclosed herein are a method for replacing vehicle parts using an in-vehicle network based on an automotive Ethernet and a system for the same. The method is configured such that a vehicle diagnosis module included in a vehicle performs vehicle self-diagnosis, such that the vehicle and a vehicle manufacturer server perform an authentication process for a new part when a vehicle part is replaced based on a vehicle part replacement agreement procedure between the terminal of a vehicle owner and the maintenance terminal of a vehicle maintenance company, and such that the terminal of the vehicle owner checks whether replacement of the vehicle part is performed normally by requesting an integrity check result from each of the vehicle and the vehicle manufacturer server when the maintenance terminal transmits a part replacement completion message to the terminal of the vehicle owner after completion of the authentication process.

Abstract: A method and apparatus for predicting the risk of the collision of an object are disclosed herein. The apparatus for predicting the risk of the collision of an object includes an information reception unit, an input processing unit, a risk calculation unit, and a provision unit. The information reception unit receives information transmitted by each of a plurality of heterogeneous transmission apparatuses. The input processing unit processes the information into input information required to calculate a degree of risk of a collision between objects. The risk calculation unit calculates the degree of risk of the collision between the objects using the processed input information. The provision unit externally outputs the degree of risk of the collision, and performs control so that the risk of the collision between the objects can be externally predicted.
