Vehicle and Vehicle Network Security Method

原文（中文）

A vehicle includes a first controller that requests a first authentication process by transmitting a previously stored first shared key ID, and a second controller that verifies validity of a shared key ID by comparing a previously stored second shared key ID with the first shared key ID according to the request for the first authentication process, and performs the first authentication process using the shared key ID of which validity has been verified, in which, when an identity is authenticated through the first authentication process, the first controller increments a value of the first shared key ID by a preset value and stores the value of the first shared key ID and the second controller increments a value of the second shared key ID by the preset value and stores the value of the second shared key ID.
