Abstract
A method of secure transmission of data signals over a bus system is described, where the data signals are generated by at least one sensor and are transmitted over the bus system to at least one actuator. The data signals generated by at least one of the sensors are encoded according to a predetermined secure encoding method before being introduced into the bus system. The encoded data signals are fed into the bus system and transmitted over it. The encoded data signals are received by at least one of the actuators and decoded according to a decoding method corresponding to the predetermined secure encoding method. In addition, an electronic monitoring system is described for carrying out this method.
