Abstract
In this paper, we suggest an extended security approach for Bluetooth’s point-to-multipoint communication. Bluetooth specification [1] defines the basic security measures like, key generation, authentication and encryption for a piconetwhich is the basic network unit of maximum 8 active Bluetooth devices. However, very little effort has been given so far on pointto- multipoint communication security in Bluetooth piconets. In this paper, we discover a Bluetooth security flaw in point-tomultipoint communication based on the master-key generation/re-generation process, for which, we suggested an appropriate prevention scheme. We analyze all possible alternative measures that can be taken before the master-key generation process starts in a master node and then we end up with an appropriate resolution. Our proposed solution expands the point-to-multipoint security and, is compatible with the existing Bluetooth Specification.
