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: An apparatus and method for processing sensitive data. The apparatus includes one or more processors and executable memory for storing at least one program executed by the one or more processors. The at least one program is configured to, in an unprotected data area, read sensitive data from a storage device and transmit the same to a protected data area using the sensitive-data storage endpoint of the protected data area; to, in the protected data area, process the sensitive data using at least one endpoint when a command for a sensitive-data service requested by a client device is received from the unprotected data area; and to, in the unprotected data area, transmit the result of processing the sensitive data to the client device.

Abstract: Disclosed herein are an apparatus and method for detecting a malicious device based on swarm intelligence. The method includes detecting a malicious device by causing at least one exploration ant to access a device swarm along movement routes in which pheromone trail values are taken into consideration, wherein the exploration ant is generated in response to a detection request received from a security management server, when the at least one exploration ant detects a suspicious device that is suspected to be a malicious device, causing the exploration ant to return along the movement routes in reverse order, and returning pheromone trail values generated by devices on the return movement routes to a malicious device detection apparatus, and identifying whether the suspicious device is the malicious device by calculating an optimal solution based on a local information set generated by aggregating the pheromone trail values returned for movement routes.
