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 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.
