| 20100008508 | METHOD FOR ESTABLISHING A SECRET KEY BETWEEN TWO NODES IN A COMMUNICATION NETWORK - A method for establishing a secret key between two nodes in a communication network, in particular in a wireless local area network (WLAN), includes concealment of the fact that a key exchange occurs, one of the nodes—first node (B)—broadcasts one or more packets (P | 01-14-2010 |
| 20090282249 | PROCESS FOR ESTABLISHING A SECRET KEY - A method for establishing a secret key for a data transmission between communication partners in a network, in particular in a personal area network (PAN), or in a body area network (BAN), wherein one or several inefficient communication partners (B) in comparison to a strong, preferably central communication partner (A) of the network, have reduced power resources, is characterized through the following steps: the strong communication partner (A) transmits a plurality of data pairs, each comprising a possible key (K | 11-12-2009 |
| 20090268909 | METHOD FOR OPERATING A WIRELESS SENSOR NETWORK - 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. | 10-29-2009 |
| 20090202057 | Method For Identifying Undesired Telephone Calls - A method for identifying undesired telephone calls (Spit/Spam over IP), preferably in a VoIP network, in which the telephone calls coming in for a telephone subscriber, the callee, from at least one calling telephone subscriber, the caller, are subjected to a test or more precisely to a statistical analysis. The method is developed in such a manner that in the framework of the test for incoming calls, the time of the receipt of each call is determined and in each case the probability that the call is undesired is determined, where for the calculation of the probability the time of the receipt of the call, or a parameter dependent thereon, is related to the temporal distribution of previous undesired calls. | 08-13-2009 |
