Abstract
A gateway may perform a challenge-response authentication process on an external device which is new and external to a vehicle connected to a vehicle access interface, based on a public key of the vehicle manufacturer and a certificate of the external device. The gateway may associate one or more roles in a role-permissions database stored in a secure repository with an identifier of the external device, based on a role indicator obtained from an extended field of the external device's certificate. The gateway may control the routing of communication traffic from the external device to a destination which is the in-vehicle network based on permissions mapped to one or more roles in the role-permissions database.
