A necessity determination unit (S210-S220) determines whether or not there is an update-requiring condition in which an access authorization policy needs to be updated. A state determination unit (S240, S250, S270) determines whether or not the state of a vehicle mounted on an in-vehicle network is a secure state in which an access authorization policy can be securely updated. Update execution units (S260, S280) update the access authorization policy when it is determined by the necessity determination unit that the access authorization policy is in the update necessity state and when it is determined by the state determination unit that the access authorization policy is in the secure state.
必要性判定部(S210~S220)判定是否处于需要实施访问授权策略的更新的需更新状况。状态判定部(S240、S250、S270)判定搭载车载网络的车辆的状态是否处于能够安全地实施访问授权策略的更新的安全状态。在由必要性判定部判定为处于需更新状况,并且通过状态判定部判定为处于安全状态的情况下,更新执行部(S260、S280)实施访问授权策略的更新。
