Abstract:
1. A data transmission path arrangement, comprising: an enabling device; a device for checking a data integrity of data transmitted from a sender side to a receiver side of the data transmission path; a first data modification device located on the sender side; a second data modification device located on the receiver side, the first data modification device and the second data modification device each have the same transmission function effecting a modification of input data into output data and are connected to the data transmission path; and a comparator located on the receiver side and connected to the data transmission path and the second data modification device; wherein the comparator compares the output data supplied by the first data modification device and the second data modification device via the data transmission path, wherein the comparator activates the enabling device when the output data of the first data modification device and the second modification device are identical, and wherein a transmission of the input data, generated on the sender side, to the first data modification device and a transmission of identical input data to the second data modification device via the data transmission path occur on the data transmission path.
