Secure multicasting is one of the major requirementsfor today’s communication arena.And for any kindof secure communication,a key-distribution schemeis the most sensible part.Being a highly promising,low-cost,and emerging wireless technology,Bluetooth has key distribution supports for securemulticasting over its unit one-hop network,piconet.Bluetooth core specification[1]defines basic securityprotocols for key generation,encryption,andauthentication for intra-piconet security.However,not much attention has been paid so far on securingmulticasting over the Bluetooth Scatternet;nevertheless,multicasting is quite a sensible aspectof modern communication arena.Here in this paper,we extend the piconets key distribution scheme topresent a new key management scheme for securemulticasting over Bluetooth Scatternets.Our keymanagement scheme is compatible to the currentBluetooth architecture design as we rely onBluetooth’s existing security algorithms to proposeour resolution.
