Chapter 14Security in Wireless Personal Area Networks
This chapter presents security techniques used in personal area networks. We will see how the ideas presented in Chaps. 12 and 13 are applied on the Bluetooth wireless personal area network (WPAN), specifically how data are protected via encryption, how authentication is performed (including key exchange), and what limitations and problems are present in the design.
