    Hi,

    I've read in some of the papers that enrcyption key is generated when 802.1x authentication is completed or as a result of 802.1x authentication. Now I am not clear upon

    2) How is encryption key generatred as a result of 802.1x authentication.
    In other words, what process generates the key, post authentication
    1) Where this key is generated? At AAA server, at authenticator or station. If it is generated at AAA server, how is it ensured that key is passed securely to authenticator and station. If it is generated simultaneously at authenticator and station ( some papers say so), how does that happen

    I am taliking about enterprise scenerio where key is generated dynamically.

    Please help me on this

    Thanks,
    Himanshu

    Hi himanshu_jain01,

    Please go to the CWNP Learning Center (link is at the top), and search on the term "chicken"

    This will pull up a whitepaper I wrote a while back that explains this topic in detail.

    Thanks,
