  • Hey guys, how are you doing?

    I need to do a question: We have 15 questions in the final of the chapter 6. The question 4 said: 

    Which key is derived from the 802.1X process or from the PSK in pre‐share networks?

    a. RSK

    b. PMK

    c. GMK

    d. PTK

    I understood that the 802.1X process or PSK in pre-share generates the PMK key. Other thing: We have a good illustration in this chapter about key hierarchy that said: PMK - Highest order 802.11 key. Derived from MSK (802.1X or PSK).


    I'm confused because the book said the correct answer is PTK (D). Can anyone explain this situation?
