Chapter 11 reviews one of the new security protocols that was developed specifically for use with existing Wi-Fi equipment. We will see that the TKIP security protocol provides a huge improvement over WEP and yet is able to operate on the same type of hardware and can even be applied to many older Wi-Fi systems through firmware upgrades. We start off with an overview of what TKIP is intended to accomplish and then work through each of the functions of TKIP in detail.
