Apparatus and method for transmission of at least of a secret parameter within a space, as well as an arrangement with at least one transmitter and a space

摘要

The invention relates to a device and a method for transmission of at least of a secret parameter within a space enclosed by sides, in which or the at least by means of a transmitter of the secret parameters wirelessly by means of electromagnetic waves in the space can be emitted and the electromagnetic waves are designed in such a way that the electromagnetic waves by the sides of the space to be absorbed in such a way that the secret parameters from the outside of the space occurring electromagnetic waves can be received only defective. Furthermore, the invention also includes an arrangement with at least one transmitter and a space, in which at least by means of a transmitter at least a secret parameters wirelessly by means of electromagnetic waves inside the space enclosed by sides can be emitted and the sides of the space are designed in such a way that the electromagnetic waves by the sides of the space to be absorbed in such a way that the secret parameters from the outside of the space occurring electromagnetic waves can be received only defective.
