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: Disclosed herein are a universal subscriber identification module card and a communication method using the same. The universal subscriber identification module card includes a Universal Subscriber Identification Module (USIM) chip, a pad, and a security chip. The USIM chip performs the user authentication of a mobile terminal. The pad electrically connects the USIM chip to the mobile terminal when the USIM chip is inserted into the mobile terminal. The security chip performs a security function for the mobile terminal independently of the USIM chip and shares the two power terminals of the pad with the USIM chip.
