 Wi-Fi Protected Access - Wikipedia, the free encyclopedia
WPA firmware upgrades have been provided for the vast majority of wireless network interface cards ever shipped; 802.11 access points sold before 2003 generally needed to be replaced.
WPA is designed to work with all wireless network interface cards, but not necessarily with first generation wireless access points.
WPA was created by The Wi-Fi Alliance, an industry trade group, which owns the trademark to the Wi-Fi name and certifies devices that carry that name.

 What's New in Security: WPA (Wi-Fi Protected Access)
A Certificate Authority Server is part of the recommended configuration, to allow WPA computers assurance that the computers with whom they share keys are who they claim.
To run WPA between two computers both must have WPA software, and all access points and wireless adapters between them, as well.
WPA computers will communicate with WEP encryption, if they cannot use WPA with a particular device.

 Wi-Fi - Wikipedia, the free encyclopedia
Although most newer wireless products support the much improved Wi-Fi Protected Access (WPA) protocol, many first-generation access points cannot be upgraded in the field and have to be replaced to support it.
Wi-Fi networks support roaming, in which a mobile client station such as a laptop computer can move from one access point to another as the user moves around a building or area.
Older access points frequently do not support adequate security measures to protect against a determined attacker armed with a packet sniffer and the ability to switch MAC addresses.

 Wi-Fi Protected Access Data Encryption and Integrity - The Cable Guy – November 2004
Wi-Fi Protected Access (WPA), as described in the Wi-Fi Protected Access (WPA) Overview Cable Guy article, is an interim industry standard that makes 802.11 wireless LAN networking secure through a firmware upgrade to 802.11-based wireless network adapters and wireless access points (APs).
WPA replaces Wired Equivalent Privacy (WEP) with the combination of the Temporal Key Integrity Protocol (TKIP), which provides data confidentiality through encryption, and Michael, which provides data integrity.
Unlike WEP, which uses a single key for unicast data encryption and typically a separate key for multicast and broadcast data encryption, WPA uses a set of four different keys for each wireless client-wireless AP pair (known as the pairwise temporal keys) and a set of two different keys for multicast and broadcast traffic.

 Upgrading to Wi-Fi protected access
WPA is a Wi-Fi Alliance snapshot of the draft IEEE 802.11i security standard.
Netgear: Free WPA firmware upgrades will be available for the ME103 802.11b ProSafe Wireless AP in July, with the WG602 54 Mbps Wireless AP, WGR614 54Mbps Cable/DSL Wireless Router, and WG511/WAG511 CardBus adapters to follow.
WPA uses the same encryption engine as WEP, which means that upgrades can be supplied as firmware upgrades instead of new hardware.

 Wi-Fi Protected Access 2 (WPA2) Overview: The Cable Guy - May 2005
Wi-Fi Protected Access (WPA) is an interim standard adopted by the Wi-Fi Alliance to provide more secure encryption and data integrity while the IEEE 802.11i standard was being ratified.
With WPA, wireless network devices could be upgraded through a firmware update because the WPA security features leveraged the existing computational facilities designed for WEP.
With WPA2, however, a wireless AP that does not have the computational facilities to perform the more complex calculations for AES CCMP cannot be upgraded through a firmware update and must be replaced.

 WPA definition - Small Business Computing Online Dictionary of IT Terms: Powered by Webopedia
Short for Wi-Fi Protected Access, a Wi-Fi standard that was designed to improve upon the security features of WEP.
WEP regulates access to a wireless network based on a computer’s hardware-specific MAC address, which isrelatively simple to be sniffed out and stolen.
The technology is designed to work with existing Wi-Fi products that have been enabled with WEP (i.e., as a software upgrade to existing hardware), but the technology includes two improvements over WEP:

 Sidebar: Getting to 802.11i - Computerworld
The current Wi-Fi Protected Access (WPA) standard is considered an improvement over the earlier 64-bit Wired Equivalent Privacy specification, adding 128-bit encryption, better key management and support for the Extensible Authentication Protocol.
An improved standard, called 802.11i, or WPA 2, is due to be ratified by the Institute of Electrical and Electronics Engineers this June.
Rapid developments in this area are leading to uncertainty about how IT managers can protect their investments while still making their WLANs as secure as possible.

 Cracking Wi-Fi Protected Access (WPA), Part 1
Still, considering how many open access points there are in America, and how much easier WEP is to crack in comparison, at least for now I feel secure using WPA and confident only the most bored hacker with the most free time will even attempt to try.
Everyone with a bit of sense can understand every encryption is crackable, depending on the computational power (either brute or intelligent) you throw at it.
In this two-part series, Seth Fogie examines the internals of WPA and demonstrates how this wireless protection method can be cracked with only four packets of data.

 John Howard, IT Pro Evangelist, Microsoft UK : WPA2 (Wi-Fi Protected Access 2)
WPA2 is also known as 802.11i - it was recently certified by the IEEE.
The Access points have either A/B or A/G. The older access points won't take the upgrade, because the onboard processor can't handle the AES encryption.
WPA is more than enough for a home environment IMHO but if you have the option of WPA2 then it's a nice to have.

 WPA: New Protection for 802.11
The new solution, called Wi-Fi Protected Access (WPA), is a subset of the still unfinished IEEE (define) 802.11i security specification and will be usable by both home and enterprise wireless networks.
The clients and access points must have WPA enabled for encryption to and from an 802.1X with Extensible Authentication Protocol (EAP) authentication server of some sort, such as a RADIUS server, with centralized access management.
The way WPA will work in the enterprise is similar to the setup of any 802.1X authentication system.

 WPA wireless security offers multiple advantages over WEP
After all, the instant you rekey an access point, none of the clients will be able to access it until they are also rekeyed.
This protocol allows key changes to occur on a frame by frame basis and to be automatically synchronized between the access point and the wireless client.
The TKIP encryption algorithm is stronger than the one used by WEP but works by using the same hardware-based calculation mechanisms WEP uses.
