The in-vehicle device is mounted on a vehicle and includes: an attack detection unit that detects a network attack on the vehicle; a wireless interface management unit that manages a plurality of wireless interfaces that perform wireless communication with the outside of the vehicle; a relay station management unit that manages relay stations that communicate via any one of the wireless interfaces; and a relay station selection unit that selects a relay station connectable to the in-vehicle device from among the relay stations managed by the relay station management unit. The wireless interface management unit includes a path switching unit that, when the attack detection unit detects the network attack, switches the communication path to a path that is different from the communication path when the network attack is detected via the relay station selected by the relay station selection unit.
车载装置搭载于车辆,包括:攻击检测部,检测针对车辆的网络攻击;无线接口管理部,对进行与车外之间的无线通信的多个无线接口进行管理;中继站管理部,对中继站进行管理,所述中继站经由任一个无线接口进行通信;及中继站选择部,从中继站管理部管理的中继站中选择能够与车载装置连接的中继站。无线接口管理部包括路径切换部,所述路径切换部在攻击检测部检测到网络攻击的情况下将通信路径切换为经由中继站选择部所选择的中继站且与检测到网络攻击时的通信路径不同的路径。
