Zigbee Technology was developed for Wireless Personnel Area Networks (WPAN), aimed at control of military applications with high security. To provide the security in Zigbee networks cryptography technique is used. Cryptography performs encryption operation before transmitting the data. Zigbee networks use stream cipher encryption mechanism. Several new stream cipher cryptography techniques are proposed, but these stream cipher techniques have shown some drawbacks. In this paper a robust and fast stream cipher encryption technique has proposed for the Zigbee communication.
