A key establishment scheme for providing secure multicasting over Bluetooth Scatternets

Secure multicasting is one of the major requirements for today's communication arena. And for any kind of secure communication, a key-distribution scheme is the most sensible part. Being a highly promising, low-cost, and emerging wireless technology, Bluetooth has key distribution supports for secure multicasting over its unit one-hop network, piconet. Bluetooth core specification Ill defines basic security protocols for key generation, encryption, and authentication for intra-piconet security. However, not much attention has been paid so far on securing multicasting over the Bluetooth Scatternet; nevertheless, multicasting is quite a sensible aspect of modern communication arena. Here in this paper, we extend the piconets key distribution scheme to present a new key management scheme for secure multicasting over Bluetooth Scatternets. Our key management scheme is compatible to the current Bluetooth architecture design as we rely on Bluetooth's existing security algorithms to propose our resolution.
