Wpa2 is used for security in wifi: Everything know about the Wpa2 and its limitation

OverView of WPA2

Wi-Fi Protected Access 2 is a network security technology commonly used in Wi-Fi wireless networks. This is an upgrade from the original WPA designed as an alternative to the older, less secure WEP technology. WPA2 has been used on all certified Wi-Fi devices since 2006 and is based on the IEEE 802.11i standard for data encryption.

If WPA2 is enabled with the strongest encryption option, everyone else within the network may be able to see the traffic, but it is mixed with the latest encryption standards.

What is the difference between WPA2 vs. WPA vs. WEP

The acronyms WPA2, WPA, and WEP are so similar that you can choose either one to protect your network, but the differences can be confusing.

The least secure is WEP, which offers the same level of security as a wired connection. WEP uses radio waves to broadcast messages for easy decryption. This is because the same encryption key is used for each data packet. If the eavesdropper analyzes enough data, an automated program can find the key (in minutes). WEP is best avoided altogether.

WPA improves WEP in that it provides a TKIP cryptosystem that scrambles encryption keys and ensures that they have not been modified during data transfer. The main difference between WPA2 and WPA is that WPA2 requires the use of a stronger encryption method called AES, which improves network security.

There are different types of WPA2 security keys. The WPA2 pre-shared key uses a 64-digit hexadecimal key. This method is commonly used in home networks. Many home routers exchange WPA2 PSK for WPA2 personal mode. They refer to the same underlying technology.

WPA2 Limitations

Most routers support both WPA2 and a separate feature called Wi-Fi Protected Setup. WPS is designed to simplify the home network security setup process, but the flaws in its implementation limit its usefulness.

If WPA2 and WPS are disabled, the attacker will have to determine which WPA2 PSK the client is using, a time-consuming process. With both features enabled, an attacker can reveal the WPA2 key simply by finding the client’s WPS PIN. This is a simpler process. Security advocates recommend disabling WPS for this reason.

WPA and WPA2 can interfere with each other if both are enabled simultaneously on the router, which could cause the client connection to fail.

Using WPA2 overloads the encryption and decryption processing, resulting in poor network connection performance. The performance impact of WPA2 is usually minimal, especially when compared to the increased security risk of using WPA or WEP, or not using encryption at all.

Why Would Someone Choose WPA?

WPA encryption methods are less secure and require shorter passwords, which weakens options. There is no enterprise solution because WPA is not secure enough to support its business use. However, if you are using older software, WPA can be used with minimal processing power, which can be a better option than WEP alternatives.

Why Would Someone Choose WPA2?

WPA2 is an updated version of WPA that uses AES encryption and long passwords to create a secure network. WPA2 has personalized and corporate options ideal for home users and businesses. However, it requires a lot of processing power and may slow down or not work at all if you are using older devices.

Whichever option works best for you, it’s important to properly secure your Wi-Fi connection and keep your device secure. If your router does not support the most secure encryption method, consider using a VPN to encrypt search results. Free VPN from Panda Security helps you browse the web safely and privately from anywhere.
