The invention relates to a method and a system for assigning information contents (IN) which, during use of a conveying means (BF), in particular an aircraft, are displayed on a user-specific output unit (AE). The system comprises an on-board server (OB), by which, within a conveying means (BF), a link to the output unit (AE) can be set up, and which is assigned to a specific conveying means (BF) via a first key pair (Sg1, Sp1). A first secret key (Sg1) from the first key pair is also stored (1) on the on-board server (OB). Then, before the use of the conveying means (BF), an application (AW) is installed (2) on the output unit (AE) and a second key pair (Sg2, Sp2) is requested (3) by the application (AW), a second secret key (Sg2) being transmitted to the application (AW). Then, available information contents (IN) are displayed on the output unit (AE), and a unique code is generated (4) for each selected information content (IN). By means of the unique code, the selected information contents (IN) are then requested by the application (AW) and, in the process, the unique code is assigned (5) a third key pair (Sg3, Sp3). A third secret key (Sg3) is encrypted with the first and second public keys (Sp1, Sp2) and assigned (6) to the on-board server (OB). The selected information contents (IN), encrypted with a third public key (Sp3), are then transmitted (7) to the output unit (AE). In this way, the information contents (IN) are assigned unambiguously and economically to a user or output unit (AE), and up-to-date information contents (IN) are available during the use of the conveying means (BF). |
