摘要
In a wireless sensor-actuator network, the communication is symmetrically encrypted, with a security authority (5) managing access to the network and handing out the key. In order to ensure a secure key allocation with simple means, the key is requested via an operating device (8), which communicates with the new subscriber device (7) to be added on the one hand and with the security instance (5) on the other hand wirelessly; the key is encrypted to the HMI device (8) and secured from there, z. B. on encapsulated transmission path 9, to be added to the subscriber device (7).
