From my understanding, AES was/is widely used for Government security of encryption. Yes AES will be better than WEP due to the fact it is more powerful. Unfortunatley, most hardware out there will not be able to handle it, and you will end up spending more money, at leaste for a home user to take advantage of it
Maybe on a business stand point, AES will benefit, but as for a home user, WEP will do the trick.

AES? What's that? It wasn't mentioned until the 2nd poster brought It up.
I belive that WPA2 is much better than WEP and AES(Whatever that is), Which is now supported by Windows XP Home & Pro. Go download the update for It If You have not already done so.
And I don't believe AES is supported by XP.
WEP do the trick? WEP is weak and has been broken from what TechTV says.

| Re: faster? It'd be more "apples and apples" to compare AES with RC4, the encryption method used by WEP.
AES succeeds 3DES as the gov'ment's encryption method of choice. A proper implementation of AES is a helluva lot more computationally efficient than 3DES. This means your PDA can now not only support WPA 2.0 but also IPSec. | |

| Upgrades Ratified in June, that means Linksys should post a firmware upgrade for my WRT54G around 2006.
I've given up on them ever implementing WPA let alone this in my 802.11b devices.

I think Linksys has implemened a WPA driver for WPC11 v2.5 and 3.0.
ZyXEL has working WPA drivers for most of their B series PCMCIA client cards. B-100, B-120, B-122 (it took a long time for them though)
Unfortunately, most vendors did not do enough effort to provide such capability.
I think once 802.11i is ratified and WPA2 is adopted it would be a good time to upgrade old 802.11b cards. | |

WPA support should be in the Radio unless the vendor is implementing host mode AP functions (processing and encrypt/decrypt raw frames in CPU environment). Most AP implement AP functions in the card firmware itself (firmware AP). They download the AP firmware to the card and card (wireless module) does the enryption and decryption. For this reason if the card firmware could be upgraded to handle AES than WPA2 upgrade could be done. | |

I believe soft radio based 802.11b/g cards should be able to support the new standard. Atheros and Broadcom 802.11b/g and 802.11a/b/g cards come to mind. | |

| WPA2 is a certified name for IEEE 802.11i WPA is a specification of Wi-Fi consortium based on draft IEEE 802.11i standard. WPA2 will be based on the final 802.11i standard.
Wi-Fi is a private industry group while IEEE is a standards body. Wi-Fi does not certify IEEE standards. They can only adopt them like they did for WPA and WPA2. They can then certify vendor products to WPA2. But that does not mean they are a body to certify IEEE 802.11 standards. | |

Well, some WLAN chipset vendors implemented AES as an proprietary extension of WPA but it is not part of WPA specification. For 802.11i/WPA2 there are more changes than simply AES. In other words,
WPA + AES <> WPA2
(However vendors that implemented AES with WPA is probably pretty close to WPA/802.11i) | |

| Re: Um... AES, TKIP, What ? After some quick google searching...
WAP is a communication protocols. Inside of it, can be used a encryption code. Or several at this point.
TKIP=A "framework" for the use of encryption. Essentially, how the two machines exchange "passwords" and verify the data.
The actual encryption code, is used using said "password" to make your data unreadable to other people.
In this case,
RC4 is the legacy code. It has been around for ages, but "everyone" uses it.
It can be "reasonably" secure within a good implementation.
Although, the big problem was WEP (802.11b) had a really bad implementation, so it could be broken in a day or so.
Developed in 1987.
RC5 (the next version) has been around for some time now in production servers (1994).
For the time being, it is secure.
[Both were created by RSA, a private company]
The AES (Advanced Encryption Standard) standard was "made" by the US government via a contest + committee. Finalized in 2001. It is considered to be very secure.
However, It is limited to sensitive but not-classified data...
The NSA probably know something that we don't... Still, that's pretty darn good. | |

1 edit | Re: Um... AES, TKIP, What ? Well, depending upon your definition. ;p
What I meant its a private company, in that is isn't a *government* organisation. That it is business operated independently of the military/CIA/whatever. (well, presumably anyway). RSA is a business, with investors.
The technology RSA invents, RSA owns. [Unless you pay royalties or the patent expires]
AES, was formed by the National Institute of Standards and Technology (NIST) using public funds (tax money). As such, anyone can use the code without paying royalties.
[»en.wikipedia.org/wiki/Advanced_E···tandard]
Edit: It looks like they changed their minds later, and you can use AES now for "top secrete" information. Providing, your using 256 bit and approved software. | |
