Wireless Question -

[bob4432]

i have a laptop that can hand either setup but my pda can only do the WPA and either TKIP or AES algorithms. by switching to just WPA and TKIP am i am much more of a security risk than when i had it setup as WPA2 w/ TKIP & AES?

thanks

With WPA you should be fine. The bigger issue I would be concerned about is TKIP vs AES. TKIP is based on the older, easier-to-crack RC4 algorithm where as AES is new and strong.

If your PDA supports AES I would run WPA/AES.

AFAIK, TKIP + AES uses TKIP to encrypt multicast traffic which may or may not be a big issue for you.

This is what it is all about.

WEP, WPA, and WPA2 - http://www.ezlan.net/wpa_wep.html

The level of your security risk is also depending on what you have on your computers (I.e if you run the World Central Bank of your PDA you are probably a target 😉 ), and your enviroment.

:sun:

wpa with AES is wpa2...wpa with TKIP is wpa1

my pda does not support aes, should i just kill its wifi uses and only use the laptop? is the algorithm that important?

WPA2 says TKIP & AES

i will just kill the pda and not use it. considering i have 4 other machines i really doubt i will use the pda to acces the net. it was more of a "see how it works" type of deal. thanks. i will also switch back to aes 🙂

WPA1 (WPA with TKIP) is pretty darn secure, I would just run that and use the pda, /shrug. It's not like the difference between WEP and WPA, which is vast.


Sorry if I was mistaken, you have to realize, I have a very ciscocentric view of wireless, and Cisco considers WPA to be a "Key Mangement" thing, seperate from encryption (for the most part, can't select WEP and WPA, invalid options). You can do WPA with AES, TKIP, TKIP+AES. All using AES are considerd WPA2 by the INtel client, broadcom client, atheros client, and the cisco AP.
