Abstract: A method for protecting a user's privacy, wherein the user operates a communication device capable of processing context and wherein the user provides context information—real context—related to one or more reference context variables to a third party, is characterized in the steps of faking at least one of the one or more reference context variables, on the basis of the faked reference context variable, gathering real context information—decoy context—related to reference context variables other than the faked reference context variable, publishing the thus generated decoy context instead of the user's real context. In addition, a corresponding communication device is disclosed.

Abstract: A method for optimizing the scanning process of a mobile terminal, the scanning process being performed by the mobile terminal in order to discover an available network to which a connection is possible, wherein at least a part of existing networks is registered to a server, wherein the server provides its information regarding the registered networks to the mobile terminal, is characterized in that the scanning period of the mobile terminal is dynamically adjusted on the basis of information provided by the server.

Abstract: 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.
