Patent ID: 8204230

Claim:
A communication device comprising: a communication connection establishing circuit configured to establish a first ad hoc network communication connection between the communication device and a second communication device and configured to establish a second ad hoc network communication connection between the communication device and a third communication device; a generating circuit configured to generate encryption parameters that are used in both a first piconet, the first piconet comprising the communication device, the second communication device and the third communication device, while the communication device is the master device of the first piconet, and in a second piconet, the second piconet comprising the second communication device and the third communication device, after the communication device has disconnected from the first piconet, wherein the generated encryption parameters used in the first piconet are to be used by the second communication device and the third communication device for encrypting and decrypting data transmitted between the second communication device and the third communication device in the second piconet via the communication connection when the communication device has left the first piconet; a signaling circuit configured to signal the encryption parameters to the second communication device via the first ad hoc network communication connection and to the third communication device via the second ad hoc network communication connection; and a disconnection circuit configured to release the first ad hoc network communication connection and the second ad hoc network communication connection.
