In terms of providing security to wi-fi, you should be very careful when choosing the level of encryption. Since 2006, WPA2 officially replaced WPA. What Is Encryption?Įncryption is the process of encoding a message or information in such a way that only authorized parties can access it and those who are not authorized cannot.

So, if you have the security settings tight and the password you set is hard to predict then you have secured your wi-fi up to a great limit. In addition, depending on your router, performance can slow down by 30 percent or more when enabling WEP or WPA. The security settings and password play an important role in the security of Wi-Fi. As with WEP, WPA reduces the processing power of the network device. Until you secure your router, you’re vulnerable to people accessing information on your computer, using your Internet service for free, and potentially using your network to commit cybercrimes. Your router should be correctly set to achieve the highest level of protection. For any router, wifi security settings are always an essential key for providing security. In a Wi-Fi the most important thing is security.

One of the most significant changes between WPA and WPA2 was the mandatory use of AES algorithms and the introduction of CCMP (Counter Cipher Mode with Block Chaining Message Authentication Code Protocol) as a replacement for TKIP (still preserved in WPA2. In terms of security, AES is much more secure than TKIP. Wi-Fi Protected Access II (WPA2) WPA has, as of 2006, been officially superseded by WPA2. In WPA, AES was optional, but in WPA2, AES is mandatory and TKIP is optional. AES aka the Rijndael algorithm is a secure, fast symmetric cipher that is easily implemented in hardware. AES encryption is even used by the government to secure sensitive government data. AES encryption uses the symmetric encryption algorithm that makes it strong enough against the security attacks. WPA uses (as describe above) TKIP/MIC Encryption. This uses the AES known as the Advanced Encryption Standard for the encryption. Referred to as WPA2 the main difference for regular user would be. It was designed to replace the WEP protocol and it uses Rivest Cipher 4 (RC4) and Temporal Key Integrity Protocol (TKIP) for encryption. It was developed by the Wi-Fi Alliance in 2003. The biggest change between WPA and WPA2 was the use of the AES encryption algorithm with CCMP instead of TKIP. 802.11i will change the WPA RC4 usage to employ AES. Wi-Fi Protected Access (WPA): Wi-Fi Protected Access (WPA) is a security protocol which is used in securing wireless networks and designed to replace the WEP protocol. There are a few encryptions available and this article will provide a complete overview of WEP vs. WPA2 became available as early as 2004 and was officially required by 2006.
