A few LEAP questions for the experts:

1. Am I missing something or is there no 4-way handshake w/ LEAP? It appears that once mutual authentication is complete and a dynamic key is generated, the AP and the STA just jump right into data exchange.

2: Does LEAP use WEP encryption?

3: What is difference between an EAPOL-Key frame for LEAP and an EAPOL-Key frame for Dynamic WEP. They appear to be identical. How would you differentiate the two?

4: Dynamic WEP keys are securely transmitted to the client by encrypting them in the KEK. How does the client get the KEK? Obviously as part of the user authnentication process, but I'm looking for a more granular answer. What is the specific message that would securely transport the KEK from the auth server to the client?

thanks in advance for any insights.

I literally just came out of the testing centre having taken the CWDP exam. The certification process opened my mind to different techniques and solutions. This knowledge can only broaden your perspective. Great job, CWNP, you have a great thing going on here.

Working through the CWNP coursework and certifications helped not only to deepen my technical knowledge and understanding, but also it boosted my confidence. The hard work it took to earn my CWNE has been rewarding in so many ways.

I want to commend you and all at CWNP for having a great organization. You really 'raise the bar' on knowing Wi-Fi well. I have learned a ton of information that is helping my job experience and personal career goals, because of my CWAP/CWDP/CWSP studies. Kudos to all at CWNP.
