  • The Temporal Key (TK) is part of the Pairwise Transient Key (PTK). The TK is the 128-bit key used to encrypt data that gets sent on the WLAN. The PTK is actually 3 keys. The TK is one of those 3 keys.

    The best resource I can recommend for free on the web is this:

    If you are willing to shell out a few bucks, get the IEEE 802.11 Handbook, Second Edition. It has everything you want to know and more about the details of these protocols.
