Using WPA for a more secure wireless connection
Wi-Fi Protected Access, or WPA, is a new, improved security standard for wireless connections. WPA has addressed the weaknesses of WEP; it was developed to create a viable alternative to WEP that is more secure than that standard. The fundamentals are the same between the standards, but WPA has improved some of the various mechanisms that plagued WEP. For example, encryption keys are now dynamic and change often automatically. Additionally, the complexity of the encryption key has also been increased to help fight off users who try to derive a key from data that they capture. One of the largest improvements in WPA is the addition of authentication to the wireless connection. Now, users have to have the right encryption settings, as well as a valid username and password, to gain access to the network.
This new standard is just starting to gain momentum. Microsoft has released a special patch for Windows XP that adds this new standard to Windows. However, installing the patch will not allow you to use this new standard. Just as with WEP, WPA is programmed into the firmware of the hardware components. In order to use WPA, you must have hardware that specifically supports it. Currently, only a few companies offer base stations and wireless adapters that support this new method of security. However, that will change in time.
The next time you are considering purchasing a wireless base station and adapter, do some research and pick one that supports WPA to ensure that your wireless communications will not be decrypted and your privacy is secure.
