Abstract

To achieve secure communication in current ZigBee networks, encrypted messages using security keys need to be shared among devices. A link key shared by two devices is used for unicast communications, where the master key is the starting point for establishing a link key. The ZigBee protocol has some limitations in end-to-end key establishment, which are discussed and an improved end-to-end key establishment scheme is presented.
