Abstract
An electronic safety system, particularly a vehicle locking system, has several safety units arranged on an object to be secured, at least one authorizing authentication element, and safety control devices with several object-side authentication element detection sensors. Signal sending devices emit a query data signal in a pertaining acquisition range, which can be received by an authentication element situated in the corresponding acquisition range. The authentication element has devices for returning an authentication response signal. According to the invention, the query data signals emitted by the detection sensors contain a sensor-specifically coded data protocol range, and the authentication element has devices for analyzing the sensor-specifically coded data protocol range of received query data signals and for generating an authentication response signal which contains a sensor-indicative data protocol range which is coded with the information as to from which detection sensors the authentication element has received a query data signal.
