The invention relates to a system arrangement which generates alternative data which can be used if the transmitted data is verified as negative, i.e. if the transmitted data is identified as incorrect. According to the invention, the data is duplicated at particularly suitable locations and is redundantly transmitted and correspondingly encoded.

This invention relates to a system arrangement that generates alternative data that can be used in the event that the transmitted data is verified as negative (i.e., if the transmitted data is identified as erroneous). According to the invention, a separate physical channel is provided, and data is replicated at particularly suitable locations, transmitted redundantly, and decoded accordingly. Various security mechanisms are integrated and linked in a cooperative manner in a specific combination of features to ensure particularly secure data transmission in vehicles. This invention specifically addresses the security requirements and hardware conditions in transportation vehicles, which are not the case for, for example, packet-switched communications. According to the proposed solution, the separate physical channel allows for redundant data transmission, thereby preventing mutual interference between transmission media. The decoding allows the receiver to identify potential errors regarding data integrity, or that data has been incorrectly transmitted or not transmitted at all. If this is identified, the redundantly transmitted data can be used at the receiver side, and the overall data transmission remains unimpaired. The invention also relates to a method that enables the provision or operation of a suitable configuration of the system arrangement. Furthermore, a computer program product having control commands for performing the method or providing or operating the system arrangement is proposed.
