A method for connecting a mobile device with a vehicle-based system is described. The vehicle based-system comprises a first device and a second device that are both in possession of a system key. For an initial connection request between the first device and the mobile device, a token pair comprising a plaintext token and an encrypted token has been provided. The encrypted token is obtainable by applying the system key to at least the plaintext token. The mobile device is connected with the vehicle-based system by receiving, for a subsequent connection request with the second device and from the mobile device, the token pair comprising the plaintext token and the encrypted token. The token pair is verified using at least the system key. The subsequent connection is accepted upon successful verification of the token pair.
