Rick:
        I think it's called WEP: Wired Equivalent Privacy.
AFAIK, there are two levels, one which uses 64-bit keys and
another which uses 128-bit keys plus RC4. Which is to say,
I can set my access point to only respond to PCMCIA cards setup
with the LAN name "Froog", and that code word is likely used
scramble a 64-bit password challenge or a 128-bit cipher.

        What I'm unsure of is if the data stream itself is
scrambled. Spread-spectrum (as used in 802.11b) has an
inherent security to it in the spreading-code. Maybe that's
what's exchanged "securely" with WEP.
        Maybe I should look at the source code already. :)
