摘要
<p>The access- or drive authorization system (1) has authorization data (B) for enabling the access or drive authorization and a mobile end terminal (2) for transmitting the authorization data to a vehicle. The end terminal has a data carrier for secure storage of the authorization data for the vehicle. A transmission link (V1) is provided for transmission of the authorization data from a database server (3) to the mobile end terminal. The transmission link is encrypted with a key (S1). Another key (S2) is transferred from the database server to the mobile end terminal over the transmission link. The authorization data are transferred from the mobile end terminal to another mobile end terminal (4) over another transmission link (V2) encrypted with the latter key. An independent claim is included for a method for controlling an access authorization or travel authorization for a vehicle by an access- or drive authorization system.</p>
