Abstract :
The use of multiple network configurations for cooperative jamming with the aim to increase the region with information-theoretic secrecy is analysed. The case with a single eavesdropper at an unknown location is investigated. A pre-master key message is broken into multiple data blocks, which are then sent for different network configurations. Provided that the secrecy capacity for a given eavesdropper´s position is positive for at least one configuration, the corresponding data block can be securely delivered to the receiver, and thus the eavesdropper can not discover the master key.
