Abstract

First transmission data of a first device is received within a lower network layer and is processed, generating first intermediate layer data of an intermediate network layer. The first intermediate layer data is processed, generating higher layer data of a higher network layer. The higher layer data is processed, generating second intermediate layer data of the intermediate network layer. The second intermediate layer data is processed, generating second transmission data received by a second device. The processing the first intermediate layer data or the processing the higher layer data includes a security function. The first transmission data, the first intermediate layer data, the higher layer data, the second intermediate layer data, or the second transmission data includes a command or an action that allows to control the second device by the first device or vice versa. The security function includes a blocking or a modification of the command or action.
