Chapter 9. Upper-Layer Authentication

This chapter reviews several of the major authentication methods. We cover in some detail the way that Transport Layer Security and Kerberos V5 work and how they can be applied to Wi-Fi network security. We also look at some newer ideas, such as ways to link together Wi-Fi LAN user authentication with cellular phone authentication.
