A method for operating a wireless sensor network, wherein the sensor network includes a multitude of distributed sensor nodes for sensing data within a pre-definable environment, and wherein the sensor nodes can exchange information via encrypted data transmissions over a radio Channel is—regarding the fact that during the operational phase of the network the Performance of changes in the network, in particular the composition of the sensor nodes that are integrated in the network, is allowed in a flexible way—characterized in that a subset of sensor nodes of the network is manipulated in order to establish a shared secret (x) by transferring a defined information to the sensor nodes of the subset over a secure out of band (OOB) Channel.
