1. A communication device comprising:
- a memory to store a device identity associated with a first radio system that identifies the communication device;
a data transmitter to support communication links with other devices; and
a communication controller configured to communicate using the first radio system and a second radio system, wherein the second radio system is different from the first radio system, the communication controller being configured to;
store an algorithm for varying the device identity;
send, via a secure channel, the algorithm or parameters used in the algorithm to another device;
negotiate the device identity with the other device, the negotiating performed out-of-band via the second radio system, and store the device identity in the memory;
periodically vary the stored device identity associated with the first radio system in accordance with the algorithm, wherein the varied stored device identity is not sent to the other device; and
communicate with the other device, via the first radio system, using the varied stored device identity.

Abstract
A communication device comprises a memory for storing a device identity; a data transmitter for supporting communication links with other devices; and a communication controller, wherein the controller is configured to periodically vary the stored device identity and to cause the data transmitter to periodically transmit the stored device identity so that the device can be identified.
