摘要： A vehicle network intrusion detection device, a system including the same, and a method thereof are provided. The vehicle network intrusion detection device includes a processor that records a receive timestamp of a controller area network (CAN) message for each CAN ID, calculates a residual, which is a difference between a real receive timestamp and an average receive timestamp of the CAN message, using the recorded receive timestamp, and determines whether there is a vehicle network intrusion based on the residual and a storage storing at least one of the CAN message receive timestamp, the residual, or the result of detecting the intrusion.

摘要： According to an aspect, a method performed by a first controller for providing security for multiple second controllers in an in-vehicle network, includes transmitting an inherent information request to a suspicious controller of the second controllers for inherent information of the suspicious controller, the inherent information request including a certificate assigned to the first controller, and receiving an encrypted inherent information of the suspicious controller from the suspicious controller, the encrypted inherent information having been encrypted with a public key associated with the certificate, and using a private key associated with the certificate for obtaining decrypted inherent information from the encrypted inherent information, and comparing the decrypted inherent information with pre-stored inherent information, and determining the suspicious controller to be an anomalous controller when the decrypted inherent information is different from the pre-stored inherent information.

摘要： A hydraulic bushing of a lower arm for a vehicle includes an inner pipe, an outer pipe, an elastic member disposed between the inner and outer pipes and connecting the inner pipe to the outer pipe, and a fluid chamber defined in the elastic member. Fluid is sealed inside the fluid chamber. A stopper protrudes radially from an outer circumference of the inner pipe toward the outer pipe. The elastic member is coupled to the stopper such that the elastic member surrounds the stopper.

摘要： According to an aspect, a method is performed by a first controller for providing security for second controllers in an in-vehicle network. An inherent information request is transmitted to a suspicious controller of the plurality of second controllers for an inherent information of the suspicious controller. The inherent information request includes a certificate assigned to the first controller. An encrypted inherent information of the suspicious controller is received from the suspicious controller and a decrypted inherent information is compared with a pre-stored inherent information. The suspicious controller is determined to be an anomalous controller when the decrypted inherent information is different from the pre-stored inherent information. In response to receiving an update request from a backend server for a specified controller out of the plurality of second controllers, the inherent information request including the certificate assigned is transmitted to the specified controller.
