摘要

Method for securing data transfer over a data bus in which data messages are sent from a transmitter to at least one receiver over a parallel data bus. Accordingly, an original data message is sent over one channel of the data bus, while a complementary message is sent over the other channel. The complementary signal is created by the transmitter, while the receiver compares the complementary signal with the original.
